The Seahawks outlasted the Steelers in a thriller on Sunday afternoon, but they lost tight end Jimmy Graham for the rest of the season along the way.

Seahawks coach Pete Carroll said in his postgame press conference that Graham tore the patellar tendon in his right knee. Graham hurt his knee while trying to catch a Russell Wilson pass in the end zone early in a wild fourth quarter in Seattle.

The severity of the injury isn’t a big surprise as the team’s medical staff immediately immobilized Graham’s knee in an aircast before loading him on a cart to head to the locker room. Graham’s season is over and his availability for training camp and the start of next season will likely be in doubt well into next summer. As we saw with Victor Cruz this year, he’ll also have to watch for other injuries as he tries to make a complete recovery and get back onto the field.

The injury came during what might have been Graham’s best game with the team. He had four catches for 75 yards and the Seahawks passing offense had its best day overall as Russell Wilson spread the ball to seven receivers on his way to a season-best 345 yards and career-best five touchdowns.

Luke Willson and Cooper Helfet are the other tight ends on Seattle’s roster at the moment and they’ll be asked to do more the rest of the way with Graham out of the picture and a playoff berth in the team’s sights.
