Rapoport: Week 10 game rankings
Quinn was speaking Wednesday for the first time since sustaining the injury Oct. 28.
He remembers taking a knee to the back of the helmet during a scramble early in the game, but he never saw the Raiders' Rolando McClain when he got sacked on the next play, and Quinn recalled having "tunnel vision" when he threw an ensuing interception.
Quinn also acknowledged sustaining a concussion in a preseason game against Green Bay. That one cleared up quickly, he said, but the latest concussion has been "lingering more."
