Tackle Jonathan Scott's minor knee injury was enough to throw a scare into the Steelers because they re-signed tackle/guard Trai Essex today to a one-year contract.
Essex, who came to them as a tackle in the third round of the 2005 NFL draft, started 25 games, some at tackle, some at guard. He opened the 2009 season He won the job and started all 16 games at right guard in 2009 and opened last season there. However, he sprained an ankle in the second game, returned to start three more games at mid-season but then lost his starting job to Ramon Foster.
Essex became an unrestricted free agent this year.
Scott left Thursday night's game with a knee injury on the first play from scrimmage. There was no ligament damage to his knee but the Steelers have no experienced backups at tackle and there even has been talk of re-signing 36-year-old Flozell Adams.
The Steelers released first-year guard Nevin McCaskill to make room for Essex on the roster.
