Murphy-Bunting has been on the Buccaneers’ practice squad but will now join the Steelers’ 53-man roster. The 29-year-old corner missed all of last season with a torn ACL but has started 65 of the 82 games he appeared in over his career while notching 11 interceptions. The addition of Murphy-Bunting could provide an upgrade to a defense that recently lost Joey Porter Jr. after trading him to the Cowboys.
