BEREA, Ohio — Browns coach Pat Shurmur defended his team’s handling of QB Colt McCoy’s injury in a loss to Pittsburgh.

McCoy sustained a concussion from a vicious helmet-to-helmet hit from Steelers linebacker James Harrison in the fourth quarter Thursday. McCoy was replaced for two plays by backup Seneca Wallace before coming back in and throwing an interception. Shurmur said McCoy didn’t show any symptoms of a concussion until after the game.

Shurmur is confident the Browns’ medical staff followed the NFL’s strict guidelines on head injuries when they assessed McCoy on the sideline.
