Former Browns quarterback Bernie Kosar says concussions suffered during his NFL career have caused him to develop a speech problem, which in turn led to his dismissal as the color commentator for Browns preseason games.

“I was informed yesterday by the Cleveland Browns and WKYC that I have been replaced as a 2014 preseason game day color commentator,” Kosar said in a statement, via Tom Reed of the Cleveland Plain Dealer. “I believe that this decision stems from my slurred speech impairment, which is a direct result of the many concussions I received while playing in the NFL.”

Kosar’s slurred speech was noticeable when he was hired for the job, however, which raises the question of why he would get fired for it now if the Browns and WKYC didn’t have any problem with his speech at the time they hired him.
