Cowboys wide receiver Roy Williams will wear a visor on his helmet for Sunday's game against the Redskins. Williams wears the visor because of his contact lenses. He was hit in the face mask with a ball during last Sunday's loss to the Packers because the visor clashed with the lights at Lambeau Field. "That [visor] is really bright," Williams said. "You can see the lights in my vision. That ball hit me dead in the face. Show me any other [pass] when I've gotten hit dead in the face."
