Referee leaves Browns-Jets game with injury

Umpire Butch Hannah took a shot while officiating the Browns-Jets game and has left the field with an injury.

Jets cornerback Antonio Cromartie accidentally ran into Hannah just before halftime, knocking him to ground. He remained on the turf for a few moments before being helped off by medical staff. He's been taken back to the locker room for further treatment and his return is questionable. There's been no word on the specifics of the injury.

Here's Cromartie delivering the inadvertent blow. After getting the first shot, Hannah then staggers into defensive lineman Muhammad Wilkerson and goes down.
