The Browns could lose cornerback Terrance Mitchell for the remainder of the season after he suffered a broken forearm in Sunday's game against the Raiders, the team said.
Medics carted off Mitchell from the field after he sustained an injury in the first half of the game.
He joined the team as a free agent this past spring.
If he does miss the rest of the season, the Browns will heavily rely on rookie cornerback Denzel Ward, T.J. Carrie and veteran E.J. Gaines.
