PITTSBURGH, Sept. 13 (UPI) -- Pittsburgh Steelers offensive tackle Willie Colon had a torn triceps muscle repaired Tuesday and will be out of action for an unspecified period, the team said.
Coach Mike Tomlin said the starter will miss "an extended period of time to say the least" and will likely go on injured reserve.
Colon, who missed all of last season with an Achilles injury, was hurt in the Steelers' loss to Baltimore Sunday.
Colon had started every game from 2007-09 after appearing in two games as a rookie in 2006.
With Colon on the shelf, Tomlin will have to rely on rookie Marcus Gilbert and second-year tackle Chris Scott.
