Oakland quarterback Derek Carr delivered a sideline stiff-arm to punctuate a short scramble -- but it might have ended his afternoon.
The second-year QB was forced to exit in the second quarter of Sunday's season opener against the visiting Cincinnati Bengals with an apparent hand injury. He was replaced by Matt McGloin.
Carr went to the locker room with trainers, and the Raiders didn't announce the extent of his injury.

Carr did miss practice time during the spring with an injured right ring finger, but it's unclear whether this injury is related.
