Redskins cornerback Josh Wilson suffered a back injury on Arizona’s first possession of the third quarter and did not return to Washington’s 22-21 victory on Sunday.

Wilson was trying to tackle Arizona running back Beanie Wells, leading with his head, when he twisted away from the play and fell to the ground face first. He lay with his face in the ground for several minutes as the training staff tended to him, and a cart appeared on the field to take him away. But Wilson got up and walked off the field – and eventually to the locker room – under his own power.

“It doesn’t look too bad right now,” Coach Mike Shanahan said after the game.

Wilson’s injury, though, left Washington with Kevin Barnes at the cornerback opposite DeAngelo Hall. Barnes later went out with what appeared to be leg cramps, but he returned. At one point in the second half, Hall was joined by reserves Byron Westbrook and rookie Brandyn Thompson in the secondary.

Outside linebacker Brian Orakpo, who dealt with a sprained ankle during the week, said the injury did not hamper him Sunday.

“I was able to move, no problem,” Orakpo said.
