Broncos receiver Bennie Fowler left the team's game Sunday against the Cowboys after taking a hard hit to his head.

Video of the injury was bad enough, but what happened afterward was worse. Fowler couldn't even walk straight as he stumbled on his way back to the sideline, collapsing twice before medical staff attended to him on the sideline.
