The question comes up every time a star player disappears from an NFL roster: what is injured reserve, really? Injured reserve, or IR, is a list teams use to hold a player’s rights while freeing up his roster spot for someone healthy. A player on IR cannot play or practice with the team until he clears a required waiting period, and in plenty of cases his season simply ends there.
Ricky Pearsall’s situation with the San Francisco 49ers shows how blunt that ending can be. Pearsall landed on injured reserve after knee surgery closed out his 2026 season, with doctors pointing to a recovery window of six to 12 months. General manager John Lynch summed up the mood inside the building: “He’s gutted. We’re gutted.”
How many players can a team put on injured reserve?
There is no cap on how many players a team can place on injured reserve over the course of a season. If a roster gets hit hard by injuries in October, the front office can keep placing players there without hitting some fixed ceiling. The limit that actually matters sits on the other end of the process, in how many of those players are allowed to come back.
Can a player return from injured reserve?
Yes, under rules the NFL and NFLPA settled on for the 2022 season and have kept largely intact since. A club may designate up to eight players to return from injured reserve, or from the reserve/non-football injury list, in a single season. It may designate the same player twice if a setback follows his first comeback attempt, and both trips count against that team total of eight. Before any of that, a player must stay on injured reserve for a minimum of four games from the date he was placed there.
What is IR-designated to return, exactly?
Once a player is healthy enough to practice again, the team formally designates him to return. That move starts a 21-day clock. During those three weeks he can practice fully with the team, and by the end of it the club has to make a call: activate him to the 53-man roster or keep him on injured reserve for the rest of the year. There is no in-between option once the window closes.
Timing also matters at the start of the year. A player placed on injured reserve before the roster cuts down to 53 and the post-cutdown waiver period closes is not eligible to return that season at all, no matter how his recovery goes.
What’s the difference between IR and reserve/non-football injury?
Standard injured reserve covers injuries or illnesses tied to football activity, the kind that happen in games or practice. Reserve/non-football injury or illness, often shortened to NFI, covers something that happened away from the team facility, such as a car accident or an illness unrelated to the job. According to NFL.com’s own explainer on roster designations, a player on the NFI list is “not entitled to receive his salary” while sidelined, a contrast with players on standard injured reserve or the physically unable to perform list, who keep collecting their pay.
What changes to IR rules for the 2026 season?
The core injured reserve numbers stay put for 2026: eight return designations per team, two uses per player, four games minimum. Owners did approve one adjustment nearby. Players on the physically unable to perform list can now begin their 21-day practice window after a team’s second regular-season game instead of at a fixed earlier point, giving clubs more room to manage a recovery that starts slow. It is a small tweak, though it shows the league still treats PUP, NFI and IR as three separate levers rather than one blanket injury list.
None of this changes the basic bargain for a player like Pearsall. Getting hurt badly enough to need surgery in August all but guarantees a lost season, cap or no cap, return designation or not.
