Josh Cribbs left Thursday night's game against the Ravens with an apparent head or neck injury and will not return. Cribbs took a shoulder to the back of the head while returning a punt and lost his helmet, then smacked the back of his head on the turf. He walked off under his own power but laid on the field motionless for a minute or two. Cribbs drew the start at receiver in place of the injured Mohamed Massaquoi.
