Injured reserve list
The injured reserve list is a designation used in North American professional sports leagues for athletes who suffer injuries and become unable to play. The exact name of the list varies by league; it is known as "injured reserve" in the National Football League and National Hockey League, the "injured list" in the Canadian Football League, the injured list in Major League Baseball and Major League Soccer, and the "PUP List" in World Wrestling Entertainment. The National Basketball Association does not have a direct analog to an injured reserve list, instead using a more general-purpose "inactive list" that does not require a player to be injured.
Injured reserve lists are used because the rules of these leagues allow for only a certain numbers of players on each team's roster. Designating a player as "Injured/Reserve" frees up a roster spot, enabling the team to add a new replacement player during the injured athlete's convalescence. Injured reserve can be for serious injuries or illnesses.
NHL rules
A player may be placed on injured reserve if he is unable to participate due to illness or injury, provided that the player had passed the club's initial physical examination at the start of the season. To qualify for the IR due to injury, that injury must be sufficient to render the player unable to participate for the seven days following that injury. Once placed on IR, the team may then replace the player on their roster. The player on IR may not return to active play for seven days, although they may participate in non-competitive events such as practice, meetings, etc. The NHL also has an LTIR list, for long term injuries. The LTIR list requires the player to be out of play for 24 days AND 10 games.NFL rules
A team may place a player on injured reserve who is "not immediately available for participation with a club". Generally, these players may not practice or return to the active roster for the rest of the season in which they are placed on injured reserve but are allowed to be with the team.Starting in 2012 the NFL and the NFLPA reached an agreement allowing one player placed on injured reserve to be brought back to the active roster. Provided that the player was on the final 53-man preseason roster and that the injury was deemed to keep this player unable to practice or play football for an estimated six weeks, the player may be allowed to practice after Week 6 and be activated to play after Week 8. In 2017 the rule was changed to allow up to two players to return from injured reserve after Week 8. In 2018 the rule was slightly modified to account for teams' bye weeks: players became eligible to return only after their team had played eight games instead of after eight weeks. In the wake of the COVID-19 pandemic, teams were allowed to re-activate an unlimited number of players after a minimum of three games each. In 2022, a limit of eight players was reintroduced, and the minimum duration increased to four games.
In 2024 teams making the playoffs were granted two additional activations for postseason use only, for a maximum of ten; any activations not used in the regular season can carry over.
Teams may also place a player on injured reserve with a minor injury designation, but the team must release the player once he is healthy.
During the preseason, the league also allows players with long-term, but not season-ending, injuries to be placed into one of three designations: physically unable to perform for injuries sustained during the previous season or during offseason training activities, reserve/non-football injury for injuries sustained outside of team or league activities, or reserve/non-football illness for severe illnesses sustained by players unrelated to football. Players on the PUP list can be moved to the active roster after Week 6 of the regular season or placed on injured reserve., players on the NFI lists can begin practicing after Week 6 but cannot be activated until their team has played eight games. When a player from the NFI list begins practicing, a three-week window starts in which they are eligible to be moved to the active roster. If the player is not activated at the conclusion of the three-week window, they must remain on the NFI list for the rest of the season. During the regular season, players on the PUP list and injured reserve do not count against the league's 53-man roster maximum, but do count against the 90-man roster limit.
NBA rules
Due to abuses in the use of the injured reserve list, where some teams found it convenient to use the IR to stash players without independent medical oversight, the injured reserve has been renamed the Inactive List with the last collective bargaining agreement. Starting in the, players can enter the inactive list one hour before tip-off for as little as one game. The inactive list has a minimum of one player and a maximum of three, subject to hardship rules when a team with three injured players already on its inactive list has a fourth player injured. Players sent to the NBA G League continues to count on a team's inactive list.WNBA rules
Unlike the NBA, the WNBA has no injury list as of the 2019 season. This notably affected the Seattle Storm going into that season, when reigning league MVP Breanna Stewart tore her right Achilles in the 2019 EuroLeague Women final. Because of the lack of an injured list, the Storm suspended Stewart without pay to free up a roster spot.The league had an injury list when it began play in 1997; players placed on this list were required to sit out at least three games. In 2006, the league changed to an inactive list of up to two players, but it was eliminated after the 2008 season, when rosters were reduced to 11. WNBA rosters now consist of 12 players.
MLB rules
There are five types of injured reserve lists in Major League Baseball.WWE rules
Within WWE, the closest functional analogue to a sports-league injured reserve system is the Physically Unable to Perform List. This designation applies to any contracted performer from the company’s main roster programs to developmental brands such as NXT and Evolve. Injuries may occur during televised matches, non-televised live events, training sessions, or other company activities. The modern use of a centralized injury-tracking designation within WWE emerged in part after several high-profile disputes in the early 2010s between wrestlers and executives regarding the handling of performer health.Once placed on the PUP list, a performer is generally removed from active in-ring competition and may also be absent from regular on-screen appearances until medically cleared. Unlike major North American sports leagues which frequently mandate minimum absence periods or provide formal “designated to return” windows. WWE does not publish fixed timelines or regulated recovery thresholds for its PUP designations. Instead, a performer’s return is determined by the combination of medical clearance from WWE’s internal medical staff and the company’s creative planning.
While listed as PUP, performers may continue to appear in non-wrestling segments such as promos, interviews, or backstage vignettes, depending on storyline needs. If they are not needed for any creative duties, they are removed from the internal roster as not to accidentally schedule and/or book them for a show while they are injured. Upon clearance, they are restored to active competition. WWE’s publicly available personnel listings define the PUP category as consisting of “talent currently out with a legitimate injury, or away from programming for other reasons,” reflecting its role as an internally managed roster-tracking tool rather than a formal regulatory mechanism. Those with injuries in kayfabe are not placed on this list.
