Cooper sustained a knee injury at the Oakland Raiders May minicamp and recently had surgery.
The PUP list is not the same as injured reserve, meaning a player cannot return even if he is physically healthy enough to do so. The PUP format is that if these individuals are not ready by the time the Raiders trim the roster to 65 players, Oakland can either extend their respective stints the PUP list through the sixth week of the regular season. At that point, there is a three-week practice window before either returning to the 53-man roster or end the season on injured reserve.
