Redskins' Norman diagnosed with concussion

Washington Redskins star cornerback Josh Norman has been ruled out for the remainder of Sunday's game against the Detroit Lions with a concussion.

Norman was taken to the locker room after he appeared to land heavily defending a 57-yard pass, with his head hitting the ground.

He stayed down for several minutes as he was attended to by Redskins trainers.

To add insult to injury, Norman was called for pass interference on the play, though the Lions declined as Marvin Jones was still able to come down with the ball.
