The Kansas City Chiefs quarterback left Sunday's 26-16 loss to the Oakland Raiders in order to be evaluated for a head injury. Quinn exited after the Chiefs' offense had 17 yards in his three drives, and did not return. He had a fumble and threw an interception.

Quinn was surprised to receive the starting nod over teammate Matt Cassel, and now Cassel has a chance to take back the job. It's hard not to feel bad for Quinn. His NFL career has seemed snakebitten wherever he has gone.
