PITTSBURGH -- Pittsburgh Steelers cornerback William Gay sustained an apparent concussion during an accidental helmet-to-helmet collision with teammate Ryan Mundy during the fourth quarter of the Oakland Raiders' 27-24 comeback victory Sunday.
As the Raiders' Louis Murphy was catching a 19-yard pass at the Steelers 40 with 53 seconds remaining, Gay and Mundy converged on the receiver at the same time, and Mundy's helmet slammed into Gay's. The cornerback lay on the turf for several minutes before being helped off the field.
Steelers coach Mike Tomlin said Gay is believed to have a concussion. Gay did not require hospitalization and was at his locker after the game.
