Sources: Steelers’ Colon suffers arm injury

The Pittsburgh Steelers not only lost badly to the Baltimore Ravens on Sunday, they might have lost one of their most important players for a significant period of time in the process.

Starting ORT Willie Colon, according to two sources, suffered an arm injury, which is believed to be in the triceps area.

If the injury is significant, and the early indication is that it is, the Steelers could re-sign veteran OT Flozell Adams, who started 16 games last season for team last season when replacing Colon, who missed all of 2010 with an Achilles tendon injury.

The top free agent offensive tackles available according to are Ryan Harris (injured/back), Jon Stinchcomb, Nick Kaczur, Mario Henderson, (former Steeler) Max Starks and Adams.

The Steelers, who host the Seattle Seahawks this Sunday, list second-year OT Chris Scott as Colon’s backup.

Colon re-signed with the team with a contract for five years and worth $29 million back in late July.
