Even the regular NFL referees couldn't prevent this one. Cleveland Browns wide receiver Josh Cribbs left Thursday night's game against the Baltimore Orioles after taking a vicious shot to the head by Ravens linebacker Dannell Ellerbe -- dislodging Cribbs' helmet and the ball -- on a first-quarter punt return.
Deadspin.com has video of the play.
Adding insult to injury, Cribbs also took a cleat to his bare head. He was able to walk off the field under his own power, but he was later ruled out for the rest of the game with, understandably, a head injury.
NFL Network's Alex Flanagan reported that Cribbs tried to convince the team's medical personnel that he was OK, but obviously they weren't buying it.
