PITTSBURGH — Steelers offensive tackle Willie Colon will have surgery Wednesday to repair a torn right Achilles' tendon and is expected to miss the season.

Colon was injured while working out on his own at the Steelers practice complex on Monday. The Steelers haven't officially ruled Colon out for the season, but such an injury typically sidelines a player for at least nine months.

Rookie tackle Chris Scott, a fifth-round pick, also will have surgery Wednesday to repair a right foot injury that occurred while he was training in Tennessee.

With Colon likely out until 2011, the Steelers will explore bringing in an experienced offensive tackle. Right guard Trai Essex also could be moved there if another player isn't signed.
