Prior to the 2019 season, the "Injured List" was known as the "Disabled List."  

There are four different types of MLB injured lists: the 7-day Injured List (for players suffering an acute concussion), the 10-day Injured List (for position-players only), the 15-day Injured List (for pitchers and for "two-way players"), and the 60-day Injured List (AKA the "Emergency Injured List").
CoViD-19 EXCEPTION: There is a special MLB "CoViD-19 Related Injured List" in 2022 for players who are diagnosed with CoViD-19 during the MLB regular season, as well as for players who exhibit symptoms and/or have been exposed to the virus, or who are in a CoViD-19 "high risk" group. A player can only be placed on the CiViD-19 Related Injured List by consent of the CoViD-19 Joint Health & Safety Committee. There is no minimum or maximum number of days a player must spend on this list, but a player may not be reinstated until he is symptom-free and tests negative for the virus twice where the tests are administered at least 24 hours apart. A player on the CoViD-19 Injured List does not count against his club's Reserve List or Active List.     
NOTE: The 15-day IL for pitchers and two-way players will be a 10-day IL through May 1, 2022. 

PLAYERS ON CUBS MLB 60-DAY IL (updated 9-8-2023) 
Nick Burdi, RHP (eligible to be reinstated 7/20)  
Codi Heuer, RHP (eligible to be reinstated 5/29)
Brandon Hughes, LHP (eligible to be reinstated 8/11)
Ethan Roberts, RHP (eligible to be reinstated 5/29)

There are only two types of minor league injured lists: the 7-day Injured List and the 60-day Injured List.

Only players with a verified injury or illness may be placed on an injured list.

The MLB Commissioner (or the Commissioner's designate) must approve all MLB Injured List assignments.

A "Standard Form of Diagnosis" signed by the club physician must accompany a request to place a player on an MLB or minor league injured list, and a "Standard Form of Diagnosis for Recertification" signed by the club physician must be filed with the MLB Commissioner after seven days for a player on an MLB 7-day (concussion) IL, every 15 days for a player on an MLB 15-day IL, every ten days for a player on an MLB 10-day IL, and every seven days for a player on a minor league 7-day IL. If a "Standard Form of Diagnosis for Recertification" is not submitted by the deadline, the player must be either reinstated from the IL or transferred to the 60-day IL.  
NOTE: A Standard Form of Diagnosis for Recertification is NOT required once a player has been placed on or transferred to an MLB or minor league 60-day IL. 

A "Return to Play" form signed by the club's physician must be submitted to the MLB Commissioner before a player can be reinstated from the MLB 7-day (acute concussion) Injured List.

There is no limit to the number of players who may be on a club's injured list(s) at any one time.

1. An ill or injured player who is placed on the MLB 7-day, 10-day, or 15-day IL or on the minor league 7-day IL does not count against his club's Active List, but he does count against his club's Reserve List.

2. A player cannot be placed on the MLB 7-day, 10-day, or 15-day IL after the conclusion of the MLB regular season and throughout the post-season, off-season, and Spring Training, and a minor league player can be placed on a minor league club's 7-day IL only during his minor league club's regular season.
EXCEPTION: With consent of the MLB Commissioner, a player on an MLB Active List (26-man roster) of a club that is active in the MLB post-season can be placed on the 7-day, 10-day, or 15 day Injured List during a post-season series.  

3. As long as the player did not appear in a game during the retroactive period (including "official" MLB Cactus League or Grapefruit League games or other MLB pre-season exhibition games), an MLB 10-day or 15-day Injured List assignment can be backdated up to three days (including the three days prior to MLB Opening Day), and a 7-day (acute concussion) Injured List assignment can be backdated up to four days (including the four days prior to MLB Opening Day).

4. If a position-player on an MLB 7-day (acute concussion) Injured List is not reinstated after spending nine days on the list he is automatically transferred to his club's 10-day Injured List, and if a pitcher on an MLB 7-day (acute concussion) Injured List is not reinstated after spending at least 14 days on the list he is automatically transferred to his club's 15-day Injured List. 
CoViD-19 EXCEPTION: The MLB 15 day Injured List (for pitchers and two-way players) has been suspended in 2021 (here will be a 10-day Injured List for position players, pitchers, and two-way players).    

5. During Spring Training and during the MLB regular season up through August 31st, an injured or ill player can be placed on or transferred to the MLB 60-day Injured List only if his club's reserve list is full, but if a player is placed on or transferred to the MLB 60-day Injured List after August 31st, the club's reserve list must be full - AND - the player must be replaced on his club's MLB Reserve List (40-man roster) by another player.

6. A player on the 60-day Injured List does not count against his club's Reserve List ir Active List roster limit. 
CoViD-19 EXCEPTION: A player on the CoViD-19 Related Injured List does not count against his club's Reserve List, Active List roster, or Club Player Pool limits.   

7. A player can be transferred from the MLB 7-day, 10-day, or 15-day Injured List to the MLB 60-day Injured List (or minor league 7-day Injured List to minor league 60-day Injured List). However, a player cannot be moved back to the MLB 7-day, 10-day, or 15-day Injured List and a minor league player cannot be moved back to the 7-day Injured List once he is placed on or transferred to the 60-day Injured List.

8. A player cannot be placed on the MLB 60-day IL after the conclusion of the MLB regular season, and during the post-season and off-season, up until the start of Spring Training (beginning on the date that pitchers & catchers are scheduled to report). A minor league player can be placed on a minor league club's 60-day Injured List only during his minor league club's regular season.

9. For a player who is transferred from the MLB 7-day, 10-day, ot 15-day Injured List to the MLB 60-day Injured List (or from a minor league club's 7-day Injured List to the minor league club's 60-day Injured List), time spent on the MLB 7-day, 10-day, or 15-day Injured List (or minor league 7-day Injured List) during the MLB regular season (or during the minor league regular season) prior to being transferred counts toward the minimum 60 days a player must spend on the 60-day Injured List. However, time spent on a minor league 7-day Injured List or minor league 60-day Injured List does NOT count toward the minimum number of days a player must spend on an MLB Injured List if a player is recalled from an optional assignment or has his contract selected and is added to an MLB 40-man roster prior to being reinstated from a minor league injured list.

10. A player who is placed on the MLB 60-day Injured List during Spring Training must spend at least the first 60 days of the MLB regular season on the Injured List (the player cannot be reinstated any earlier than the 61st day of the MLB regular season).

11. A player who was placed on the an MLB 7-day, 10-day, or 15-day Injured List during the MLB regular season must be reinstated no later than the day after the conclusion of the club's MLB season  (including the post-season for clubs that qualify for the post-season), a player on an MLB 60-day Injured List who is eligible to be an Article XX-B MLB free-agent must be reinstated from the Injured List no later than 9 AM (Eastern) on the day after the final game of the World Series (or no later than 9 AM Eastern on October 15th if the World Series is cancelled), and all other players on an MLB 60-day Injured List must be reinstated no later than 5 PM (Eastern) on the 5th day after the final game of the World Series (or no later than 5 PM Eastern on October 15th if the World Series is cancelled), even if the player did not spend at least 60 days on the 60-day IL.
CoViD-19 EXCEPTION:  A player on the MLB CoViD-19 Related Injured List who is eligible to be an Article XX-B MLB free-agent must be reinstated no later than 9 AM (Eastern) on the day after the final game of the World Series (or no later than 9 AM Eastern on October 15th if the World Series is cancelled), and all other players on an MLB CoViD-19 Injured List must be reinstated no later than 5 PM (Eastern) on the 5th day after the final game of the World Series (or no later than 5 PM Eastern on October 15th if the World Series is cancelled),

12. A minor league player cannot be placed onto or transferred to a minor league 60-day Injured List until the player has spent at least five days on the club's Domestic Reserve List. 

13. A player on a minor league club's 60-day IL must be reinstated no later than 5 PM (Eastern) on the 5th day after the conclusion of the World Series, even if the player did not spend 60 days on the Injured List. 

A player on an injured list can be traded, even if the player is not eligible to be reinstated and/or healthy enough to play. 

If a player on an injured list is traded, the player can be transferred directly from his former club's 7-day, 10-day, 15-day, or 60-day Injured List to the corresponding Injured List of his new club. Time spent on a 7-day, 10-day, 15-day, or 60-day Injured List prior to the trade counts toward the minimum number of days required before the player is eligible to be reinstated.

If a player on an MLB 60-day Injured List or CoViD-19 Injured List is claimed off waivers after the conclusion of the MLB regular season but prior to the deadline for reinstating players from the 60-day or CoViD-19 injured lists, the player can be transferred directly to the 60-day Injured List or CoViD-19 Injured List of his new club.

A player accrues one day of MLB Service Time for each day of the MLB regular season spent on an MLB Injured List.

An MLB player can be placed on the Major League Bereavement/Family Medical Emergency List when the player leaves his club as the result of a death or medical emergency in his immediate family (spouse, child, grandchild, parent, grandparent, or sibling).

A player can be placed on the Bereavement/Family Medical Emergency List any time during the MLB regular season and post-season.  

A player must remain on the Bereavement/Family Medical Emergency List for at least three days, but no more than seven days.

A player cannot be placed on the Bereavement/Family Medical Emergency List to attend the birth of a child (see Major League Paternity Leave List), but a player can be transferred from the Paternity Leave List to the Bereavement/Family Medical Emergency List if the childbirth results in a death or medical complication. For players who are transferred from the Paternity Leave List to the Bereavement/Family Medical Emergency List, time spent on the Paternity Leave List counts toward the maximum number of days permitted to be spent by the player on the Bereavement/Family Medical Emergency List.

The Family Medical Emergency List functions just like the 7-day or 10-day Injured List, in that a player on the Bereavement/Family Medical Emergency List does not count against his club's Active List, so he can be replaced by another player while on the Bereavement/Family Medical Emergency List. He does count against his club's Reserve List (40-man roster), however,

A player on the Bereavement/Family Medical Emergency List continues to accrue MLB service time.

A player can be placed on the Major League Paternity Leave List when he leaves his club to attend the birth of his child. The childbirth must be either imminent or have occurred within the previous 48 hours.

A player can be placed on the Paternity Leave List any time during the MLB regular season and post-season.

A player must remain on the Paternity Leave List for at least 24 hours, but no more than 72 hours.

A player can be transferred from the Paternity Leave List to the Bereavement/Family Medical Emergency List if the childbirth results in a death or medical complication. For players who are transferred from the Paternity Leave List to the Bereavement/Family Medical Emergency List, time spent on the Paternity Leave List counts toward the maximum number of days permitted to be spent by the player on the Bereavement/Family Medical Emergency List.

The Paternity Leave List functions like the 7-day or 10-day Injured List, in that a player on the Paternity Leave List does not count against his club's Active List, so he can be replaced by another player while on the Paternity Leave List. He does count against his club's Reserve List (40-man roster), however.

An MLB player continues to accrue MLB service time while on the list.

The Temporarily Inactive List is for minor league players only.

It is essentially an in-season excused Leave of Absence, and it is used for Paternity Leave, Bereavement Leave, and Family Medical Emergency Leave, as well as when a player is delayed reporting to a new club, or is attending college, or is incarcerated, or has returned home for personal reasons. Only minor league players (including players on Optional Assignment to the minors) can be placed on this list.

A player on the Development List counts against the in-season minor league 180-man Domestic Reserve List or 70-man International Reserve List (or MLB 40-man roster if the player is on Optional Assignment), but he does not count against the minor league club's Active List roster. 
NOTE: If the Domestic or International Reserve List is full, a player who ordinarily would have been placed on the Temporarily Inactive List can be placed on the Restricted List instead, but placing a player on the Restricted List does require the approval of the MLB Commissioner).

A player cannot be placed on the Temporarily Inactive List any earlier than the first day of his minor league club's regular season, the player must remain on the Temporarily Inactive List for at least three days, and a player on the Temporarily Inactive List must be reinstated no later than the day after the conclusion of his club's season.

A player normally is not paid while on the Temporarily Inactive List (club option).

With approval of the MLB Commissioner, a player on a minor league Domestic Reserve List can be placed on the Development List if the player is at the parent organization's Minor League Spring Training Complex or at a club-approved training facility for the purpose(s) of development and/or conditioning.
NOTE: As part of his development and/or conditioning, a player on the Development List can remain with his minor league club and take batting practice, fielding practice, throw bullpen side sessions, and/or serve as a bullpen catcher, batting practice pitcher, or base coach.    

A player on Optional Assignment from an MLB Reserve List (40-man roster) can be placed onto the Development List of the minor league affiliate to which he has been optioned, but only with consent of the player.  

A player cannot be placed on the Development List for the purpose of injury rehabilitation or disciplinary action.

A player can be placed on the Development List only during his minor league club's regular season, the player must remain on the Development List for at least seven days, and the player must be reinstated from the Developmental List no later than the day after the conclusion of his minor league club's season.

A player on the Development List counts against the in-season minor league 180-man Domestic Reserve List (or MLB 40-man roster if the player is on Optional Assignment), but he does not count against the minor league club's Active List roster.  

If a player is injured while on the Development List, the player must be transferred to a 7-day IL or 60-day IL. Days spent on the Development List prior to the injury count toward the minimum number of days the player must spend on the IL before he is eligible to be reinstated.

A player is paid by the MLB club while he is on the Development List.  

A player who submits written notice of retirement while under contract to a club or while under club control can be placed on the Voluntary Retired List.

A player on the Voluntary Retired List does not get paid while on the list, does not accrue service time, and does not count against the club's Active List or Reserve List.

A player on the Voluntary Retired List must spend at least 60 days of the regular season on the list before he can apply for reinstatement. If the player is placed on the Voluntary Retired List within 60 days of the conclusion of the regular season, the balance of the 60 days would carry-over into the next season.

If an MLB player on the Voluntary Retired List is reinstated during the MLB regular season, he may consent to a "conditioning" assignment (with or without pay - TBD) with a minor league affiliate of his club for up to 30 days prior to being reinstated. 
NOTE: A player receives MLB meal money and other benefits associated with being an MLB player while on a minor league "conditioning" assignment.  

A player on an MLB Voluntary Retired List cannot be reinstated during the period of time extending from August 1st through October 31st, and a minor league player on the Voluntary Retired List cannot be reinstated during the period of time extending from August 1st through the conclusion of the season (including post-season). 

The Restricted List is essentially an excused but unpaid absence, although in certain circumstances a club might choose to pay the player while he is on the Restricted List.

If a club requests that a player be placed on the Restricted List, the request must be approved by the MLB Commissioner. 

A player who is suspended for violation of the MLB-MLBPA Joint Drug Prevention and Treatment Program (player tested positive for a prohibited substance) or is suspended or granted a leave of absence related to a violation or possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse Policy is automatically placed on the Restricted List by the MLB Commissioner.

A player placed on Administrative Leave pending investigation of a possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse policy is automatically placed on the Restricted List while he is on Administrative Leave. The player is paid and accrues MLB Service Time while on Administrative Leave. The MLB Commissioner has up to seven days to complete its investigation and determine if there was a violation, but with consent of the MLBPA, the investigation can be extended seven additional days (14 days total). After the completion of the investigation, the MLB Commissioner can find there was no violation, or find there was a violation and impose discipline in the form of an unpaid suspension (length TBD), or find there was a violation but defer disciplinary action to a later date.  

Besides a suspension related to a violation of the MLB-MLBPA Joint Drug Prevention and Treatment Program or a suspension or leave of absence related to a violation or possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse policy, other reasons why a player might be placed on the Restricted List would include an absence due to an illness or death in the family where the absence exceeds the Major League Bereavement/Family Medical Emergency List seven-day maximum limit, failing to report to Spring Training, or if a player is dealing with a personal legal matter, or is serving a prison sentence, attending college, or pursuing a career in another sport or profession, or if a player from a foreign country is unable to secure a work visa.
CoViD-19 EXCEPTION: An MLB or minor league player not in a CoViD-19 "high risk group" who opts-out of playing because of the threat of possibly contracting CoViD-19 or any player who is denied entry into a state or a foreign country because he is not vaccinated will be placed on the Restricted List and will not be paid and will not accrue MLB Service Time.  

A player on the Restricted List does not count against his club's Active List or Reserve List, and a player who is on the Restricted List for any reason other than a suspension related to a violation or possible violation of the Joint Domestic Violence, Sexual Assault, and Child Abuse policy does not accrue MLB Service Time while on the Restricted List. A player who is placed on Administrative Leave pending investigation of a possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse policy continues to be paid and will accrue MLB Service Time while on the Restricted List.     
NOTE: Beginning in December 2016, an MLB player suspended as the result of a violation of the Joint Drug Prevention and Treatment Program will receive credit for MLB Service Time while on the Restricted List if the player was on an MLB Active List or MLB DL at the time of the suspension, it's the player's first or second positive test, and the length of the suspension is subsequently reduced by at least 20 games by an arbitrator as the result of mitigating circumstances.

A player who is on the Restricted List as the result of a suspension related to a violation of the MLB-MLBPA Joint Drug Prevention and Treatment Program (ban on the use of a prohibited substance) or for a suspension or leave of absence related to a violation or possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse policy may consent to participate in Spring Training (MLB and/or Minor League Camp) and/or Extended Spring Training and/or in a post-season Instructional League (without pay), but a suspended player is not eligible to participate in the Arizona Fall League (AFL).

Prior to being reinstated, an MLB player who is on the Restricted List for any reason other than a suspension related to a violation of the MLB-MLBPA Joint Drug Prevention and Treatment Program (ban on the use of a prohibited substance) or a suspension or leave of absence related to a violation or possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse policy may consent to a "conditioning" assignment (with or without pay - TBD) with a minor league affiliate of his club for up to 30 days, and an MLB player who is on the Restricted List as the result of a suspension related to a violation of the MLB-MLBPA Joint Drug Prevention and Treatment Program (ban on the use of a prohibited substance) or a suspension or leave of absence related to a violation or possible violation of the MLB-MLBPA Joint Domestic Violence, Sexual Assault, and Child Abuse policy may consent to a "conditioning" assignment (without pay) with a minor league affiliate of his club for no more than six days for a suspension of 10-20 games, no more than ten days if suspended 21-30 games, no more than twelve days if suspended 31-50 games, and no more than 15 days for suspensions of more than 50 games.
NOTE: A player receives MLB meal money and other benefits associated with being an MLB player while on a  minor league "conditioning" assignment.  

An MLB player who is on the Restricted List for any reason other than extended Bereavement/Family Medical Emergency Leave or a suspension for violation of the Joint Drug Prevention and Treatment Program (ban on the use of a prohibited substance) or a suspension or leave of absence related to a violation or possible violation of the Joint Domestic Violence, Sexual Assault, and Child Abuse policy cannot be reinstated from the Restricted List during the period of time extending from August 1st through October 31st without the approval of the MLB Commissioner, and a minor league player on the Restricted List for any reason other than a suspension for a violation of the Joint Drug Prevention and Treatment Program (ban on the use of a prohibited substance) cannot be reinstated from the Restricted List during the period of time extending from August 1st through the conclusion of his club's season (including post-season) without the approval of the MLB Commissioner. 

A player on the Restricted List must be added back to his club's Reserve List within 30 days after being reinstated or when he is placed on the club's Active List (whichever comes first) if the player is reinstated during the period of time beginning on the mandatory Spring Training reporting date and extending through the last day of the regular season, or within 14 days after reinstatement if the player is reinstated during the off-season, but if the player is assigned to another club while on the Restricted List he must be placed on that club's Reserve List immediately after reinstatement.

PLAYERS ON CUBS MLB RESTRICTED LIST (updated 10-20-2022):
NONE 

A player can be placed on the Military List after being called to active duty (this includes foreign players called to active duty with their home country's military).

1. A player on the Military List does not count against his club's Active Roster or Reserve List, but the player does accrue MLB Service Time.

2. A player can be placed on his club's Military List within 15 days of the date he is scheduled to report for duty, but only if the player is no longer physically with the club.

3. A player on the Military List must be reinstated within 15 days after being released from service.

4. A player on the Military List can spend up to 15 days on a minor league "conditioning" assignment (with pay and full MLB benefits for MLB players) prior to being reinstated to an MLB or minor league reserve list. 

5. A player who is reinstated from the Military List after the MLB Rule 5 Draft but prior to MLB Opening Day does not count against his club's Reserve List until MLB Opening Day, or up to 15 days after MLB Opening Day if the player is on a minor league "conditioning" assignment during that period of time.   

The MLB Commissioner may place a player on the MLB Suspended List and a minor league president may place a minor league player on the minor league's Suspended List.

If a club requests that a player be placed on the club's Suspended List, the request must be approved by the MLB Commissioner.

An MLB player or minor league player who is placed on his league's Suspended List counts against his club's Reserve List and Active List, but an MLB player or minor league player who is placed on his club's Suspended List does not count against his club's Active List and Reserve List.

A player on the Suspended List is not paid while on the list but does continue to accrue MLB or minor league service time.

The main instance where it is used is when a player is suspended by the league as the result of an on-field incident, but it can also be initiated by the player's own club in the case of insubordination, unacceptable behavior (such as a player getting into an altercation with his manager, a teammate, or a fan), or a violation of team rules related to chronic tardiness, possession of alcohol or reporting to work intoxicated, missing a doctor's appointment, or failure to get into playing condition within 60 days after start of MLB Spring Training or Minor League Spring Training. (The Suspended List is used more liberally in the minor leagues, mainly because minor league players don't have the protection of a union).
NOTE: When an MLB player is placed on the Suspended List, a grievance is usually filed by the Major League Baseball Players Association (MLBPA) on behalf of the suspended player because the player does not get paid while on the list.

A player can be placed on the Disqualified List if he violates the terms of his contract (for example, player signs a contract using a false name and/or DOB, or player signs a contract with another professional baseball team without permission of an MLB club while still under contract with that MLB organization, or player circumvents a drug test, or player refuses to undergo an examination by a physician as directed by the club, or player refuses to render services to the club).

A player can be placed on the Disqualified List only with the approval of the MLB Commissioner.

A player on the Disqualified List does not count against the club's Active List or Reserve List, and he does not accrue service time or get paid while on the list.

An MLB player on the Disqualified List cannot be reinstated during the period of time extending from August 1st through October 31st and a minor league player on the Disqualified List cannot be reinstated during the period of time extending from August 1st through the conclusion of his club's season (including post-season) without the approval of the MLB Commissioner.

A player reinstated from the Disqualified List must be added back to his club's Reserve List within 30 days if he is reinstated prior to the conclusion the season, or by Opening Day if the player is reinstated during the off-season.

If an MLB player on the Disqualified List is reinstated during th MLB regular season, he may consent to a "conditioning" assignment (with or without pay - TBD) with a minor league affiliate of his club for up to 30 days prior to being reinstated to the MLB Reserve List.
NOTE: A player receives MLB meal money and other benefits associated with being an MLB player while on a  minor league "conditioning" assignment.  

If a player is assigned to another club after reinstatement he must be placed on that club's Reserve List immediately.

The MLB Ineligible List is the "capital punishment" of baseball, reserved for individuals who have been indefinitely or permanently banned from baseball, usually related to "throwing" games, betting on baseball, or consorting with gamblers, but it also could involve something like embezzlement of funds, or a significant drug-related offense, or a hate crime, or some heinous activity.

Individuals are placed on the Ineligible List by the MLB Commissioner, and once placed on the Ineligible List a player must remain on the list for at least one year.

A player on the Ineligible List does not count against his club's Active List or Reserve List, and he does not accrue service time or get paid while on the list.

An MLB player on the Ineligible List cannot be reinstated during the period of time extending from August 1st through October 31st and a minor league player on the Ineligible List cannot be reinstated during the period of time extending from August 1st through the conclusion of his club's season (including post-season). 

A player reinstated from the Ineligible List must be added back to his club's Reserve List within 30 days if he is reinstated prior to August 1st, or by Opening Day if the player is reinstated during the off-season.

If an MLB player on the Ineligible List is reinstated during the MLB regular season, he may consent to a "conditioning" assignment (with or without pay - TBD) with a minor league affiliate of his club for up to 30 days prior to being reinstated to the MLB Reserve List. 
NOTE: A player receives MLB meal money and other benefits associated with being an MLB player while on a  minor league "conditioning" assignment.  

If a player is assigned to another club after reinstatement he must be placed on that club's Reserve List immediately.
