Steelers OT Colon has surgery for torn triceps

Pittsburgh, PA (Sports Network) - Pittsburgh Steelers starting offensive tackle Willie Colon had surgery Tuesday morning to repair a torn triceps muscle.

Colon will miss "an extended period of time to say the least," Steelers head coach Mike Tomlin said.

Tomlin said Colon, who missed the entire 2010 season with an Achilles injury, would probably be placed on injured reserve.

Colon was injured late in Sunday's 35-7 loss to the Baltimore Ravens. He signed a five-year, $29 million contract after the lockout and had been a key member of what is quickly becoming a patchwork offensive line protecting quarterback Ben Roethlisberger.

Before missing all of last season, Colon had started all 16 games in the previous three campaigns after appearing in two as a rookie in 2006.

Rookie Marcus Gilbert and second-year tackle Chris Scott are listed behind Colon on the depth chart.
