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 joins the Browns having played 21 NFL games and logging 34 catches for 261 yards and two touchdowns.
He spent last season on the Eagles practice squad and took part in Philadelphia’s offseason program before being waived last weekend.
Off the field, Miller heads an organization called Charg1ng that has held youth football camps the past three years.
Miller gives the Browns two former Buckeyes on the roster, joining cornerback Denzel Ward.
A.J. Oullette, a running back from Covington who had a standout career at Ohio University, is also on the Browns roster as an undrafted rookie free agent.
