The Browns also cut Covington High School graduate A.J. Ouellete, a former Ohio Bobcats star who signed with the team team in July.
A five-star quarterback, Miller led the Warriors to the Division I Ohio state championship game in 2010 before enrolling early at Ohio State, where he was a three-year starter at quarterback and won the Chicago Tribune's Silver Football as the Big Ten Most Valuable Player twice.
A shoulder injury caused him to miss the 2014 season, and he came back as a receiver in 2015.
The Houston Texans drafted him at that position the following spring, but he has not had much success at the pro level yet.
Miller has played in 21 NFL games and logged 34 catches for 261 yards and two touchdowns.
