Several NFL teams have placed key players on the physically unable to perform (PUP) or non-football injury (NFI) lists as training camps begin. The Seahawks' Cameron Young, Jets' Mike Williams, and Browns' Nick Chubb start camp on the PUP list due to injuries from last season, with varying recovery timelines. The Packers' Kitan Oladapo, Bears' Kiran Amegadjie, Chargers' Junior Colston, and Chiefs' BJ Thompson are on the NFI list due to injuries sustained outside team activities. Recovery and return timelines remain uncertain, but teams are cautiously optimistic about activating these players for the regular season.
