Ian Rapoport is reporting that Tampa Bay Buccaneers running back Doug Martin could miss the remainder of the 2013 season with a torn labrum.
Martin fell awkwardly on his shoulder as he was being tackled. It was speculated he separated his shoulder but has been confirmed that it’s not. It’s much worse.

RB Doug Martin has a torn labrum in his left shoulder but the Bucs will not place him on IR right away. They're hopeful he can return.
