The Pittsburgh Steelers have gathered in Latrobe for training camp. Six members of the team will begin the journey on the physically unable to perform list.
Hampton and Mendenhall are both recovering from torn ACLs. Starks, who re-signed with the Steelers last week, also is working his way back from an ACL tear.
Worilds had offseason wrist surgery, and Harrison missed time during OTAs with some sort of leg injury.
Teams have no obligation to provide any specific injury information until the first week of the regular season. The six players on the PUP list can emerge at any time during training camp or the preseason. If not ready to go by the final roster cuts, the players would land on the PUP list for at least six weeks of the regular season.
