A team may place a player on injured reserve (reserve/injured list) 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 (including postseason games or the Pro Bowl) 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 (a rule exempted for the 2012 season) 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 (PUP) for injuries sustained during the previous season or during offseason training activities (a player who passes their physical at the beginning of training camp and practices is physically able to participate and is thus ineligible for the PUP list), reserve/
non-football injury (NFI) for injuries sustained outside of team or league activities (despite the name, this includes lingering injuries from
college football play, should an injured player be drafted and join the team), or reserve/non-football illness (NFI) 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==
