As boos cascaded down from the FedEx Field stands, teammates kneeled around quarterback Robert Griffin III who was receiving medical attention from trainers.

The boos didn’t continue once the realization was that Griffin may be injured.

Griffin, who had been sacked three times in the three previous drives and had taken three big hits after passing, fumbled the ball as he looked to run.

As he dove to regather the fumble, Detroit Lions defensive end Corey Wootton landed on the outstretched Griffin.

Griffin is being evaluated for a right shoulder injury and possible concussion.

UPDATE: Griffin has been ruled out.
