As if losing 20-6 to the Chargers on Sunday wasn't bad enough, the Raiders appear to have lost wide receiver Martavis Bryant for a significant period of time.
Bryant left Sunday's game with a knee injury and did not return. After the game, Raiders coach Jon Gruden said the team is "really concerned" about Bryant, and for good reason.
Bryant suffered a "possible PCL tear, according to NFL Network's Ian Rapoport.
Bryant, who caught three passes for 17 yards before leaving the game, ranks third among Raiders receivers with 19 catches for 266 yards this season, despite missing two games. An extended absence for Bryant likely would mean more reps for Seth Roberts, Dwayne Harris and Marcell Ateman.
Roberts and Harris are veterans, and Ateman is a rookie who was called up from the practice squad after the Raiders traded Amari Cooper to the Dallas Cowboys three weeks ago.
