Kosar tweeted out that his "services are no longer desired or needed" on Sunday morning.
Earlier in the week, Kosar said on his own radio show that he bet $19,000 on the Browns, though he noted he would be giving the winnings to charity. Kosar wore the No. 19 when he starred with the Browns during the 1980s.

"Earlier this week we notified Bernie, that per league policy, we were required to remove him from our pregame radio coverage for the season finale after he violated the NFL gambling policy by placing a bet on an NFL game," the Browns said in a statement. "We understand what Bernie means to this community and our history but as team contracted personnel hired to provide content on our media platforms, his bet was a violation of NFL rules and we must adhere to all NFL policy."
The Browns went on to lose 28-14 to the Steelers.
