UPDATE
Mark Walton has entered the game, so he appears to be fine.
The Bengals’ backfield continues to get depleted, as Mark Walton is now being evaluated for a concussion.
The injury happened late in the third quarter on a pass Walton attempted to catch at the sideline, but as he dove for the ball, he was hit in the helmet by Falcons safety Brian Poole, who was flagged for unnecessary roughness.
Walton went to the sideline to be examined by trainers, and the team has since announced he is being evaluated for a concussion.
