Seahawks TE Jimmy Graham out for season with torn patellar tendon

SEATTLE -- Tight end Jimmy Graham suffered a torn patellar tendon in his right knee injury in the end zone early in the fourth quarter of the Seattle Seahawks game against Pittsburgh on Sunday.

Graham was reaching back for a pass in the end zone when his right ankle buckled, causing him to fall awkwardly. Trainers were looking at his right knee. A medical cart was brought onto the field to help get Graham into the locker room.

Coach Pete Carroll said after the game the seasons-ending injury will require surgery.

"Obviously, to lose him really hurts," Seahawks quarterback Russell Wilson said.

The injury is a crippling blow to the Seattle offense as backups Luke Willson and Cooper Helfet have had some big games, but neither is as big a part of the passing game as Graham had the potential to be.
