The Colts signed veteran OG Trai Essex and waived OT Mike Person and C A.Q. Shipley, the team announced Monday.
Essex has appeared in 76 regular-season games with 28 starts and six postseason games with the Steelers. He played for Pittsburgh from 2005-11 and was cut when rosters were trimmed to 53 players.
Essex played in all 16 games last season with three starts. He provides insurance for the Colts’ O-line, as OT Winston Justice suffered a concussion in Week One.
Shipley signed with Indy in January and appeared in Sunday’s loss to the Bears. Person was claimed off waivers on Sept. 1.
