Cleveland Browns head coach Pat Shurmur confirmed that return man Joshua Cribbs left Thursday night's game with a concussion after taking a big hit on a punt return with 5:07 remaining in the first quarter. The Browns lost 23-16 to the Baltimore Ravens.
Cribbs crumpled between two Ravens players, lost his helmet, took an additional blow on the turf when his head whipped to the ground and he fumbled on the play.
Shurmur added that the team just has to wait and see where Cribbs is at in his recovery going forward, which is a vague response that makes perfect sense in light of the NFL's new concussion policy and the emphasis on player safety in any situation of suspected head trauma.
Cribbs has been a small part of the offense so far in 2012, catching just four passes for a total of 39 yards, but his bigger contributions have come by being a return threat on punts and kicks in the special-teams phase.
He has returned 11 punts for 144 yards and 12 kickoffs for 341 yards over the first four games of the season.
