The Ravens have signed Jaquan Amos, an undrafted safety from Ball State.
The 6-foot-1, 200-pound Amos had 95 tackles and five passes defended last season after transferring from Iowa State. He spent his first three collegiate seasons at Villanova, where he had 148 tackles, eight interceptions and four touchdowns as a physical safety who excelled defending the run.
In another roster move, the Ravens have released Levi Bell, an undrafted defensive lineman/fullback from Texas State.
