The Physically Unable to Perform (PUP) list is a roster designation used in the National Football League (NFL) for players who suffered injuries during football-related activities prior to the start of training camp. Players on the PUP list may participate in team meetings and use team training and medical facilities, but cannot practice with their team. There are two separate PUP lists: an active PUP list used prior to the start of the regular season, and a reserve PUP list used during the regular season.
Players can be moved off the PUP list to the active roster at any time prior to the start of the regular season, even after one practice. However, a player cannot be placed on the PUP list once he has taken the field for a practice or game. If a player is still on the PUP list at the end of training camp, he must be placed on the reserve PUP list, released, traded, or counted against the 53-man roster. Players on the reserve PUP list must sit out the first six weeks of the regular season, but they can return to practice after the first six weeks and can be activated to the 53-man roster at any time during the following six weeks.
