OT Trai Essex announced on Thursday via Twitter that he is re-signing with the Steelers. Terms and conditions of the deal were not announced.
"I am ecstatic to announce that I am back with the @Steelers! There is no place like #SteelerNation #EverydayIsABlessing", Essex tweeeted.
Set to enter his eighth NFL season, Essex has played his entire career with the Steelers. He has made 28 career starts, including three last season.
Pittsburgh lost OT Jamon Meredith to the Buccaneers earlier in free agency, so Essex provides important insurance for the team.
