Indianapolis announced Monday that Bradshaw had been put on the injured reserve list. The Colts (6-5) re-signed running back Zurlon Tipton to replace Bradshaw on the roster ahead of Sunday's game at Pittsburgh.
Tipton was cut last week when the Colts claimed another running back, Daniel Herron, off waivers.
Bradshaw spent 2013 and 2014 with Indy, but he finished both seasons on injured reserve. The Colts re-signed Bradshaw on Oct. 14. He played in six games, had 31 carries for 85 yards and caught 10 passes for 654 yards and three TDs.
