Joseph was released by the Raiders on Tuesday, Vic Tafur of The Athletic reports.
It appears rookie second-round pick Trevon Moehrig won the starting free safety role, meaning Joseph will get an opportunity to sign elsewhere as a free agent. The 2016 first-round pick played 14 games for the Browns last year and recorded 67 tackles (46 solo), four pass breakups and an interception. He'll add dependable secondary depth with another team.
