Washington Redskins left tackle Trent Williams has left in the first quarter against the Tampa Bay Buccaneers with a sprained right knee.

The Redskins said Williams' return Sunday was questionable.

Williams, a two-time Pro Bowl selection, was blocking on a third-down play when his right leg appeared to get knocked into by Bucs defensive lineman Gerald McCoy. Williams stayed down on the ground for a couple of minutes, then favored his right leg as he was helped to the sideline.

Moments later, Williams limped as he walked toward the tunnel leading to the locker room. When Washington got the ball next, Morgan Moses was in at left tackle.

Williams and McCoy were college teammates at Oklahoma and were drafted consecutively in the first round in 2010.
