Video: Derek Carr Leaves Game With Back Injury

Derek Carr slid awkwardly into a sack from Broncos DE Adam Gotsis. He immediately started grabbing his back. Though he was able to walk off the field under his own power, EJ Manuel entered the game for the Raiders. The CBS cameras showed him watching gingerly to the locker room. This situation certainly bears monitoring.

Update: The Raiders have announced that Carr has a back injury and is questionable to return.
