A rough week got rougher for the Steelers. 

Ed Bouchette is reporting via Twitter starting RT Willie Colon has a torn triceps muscle, and will have surgery Tuesday. 

Bouchette tweeted the Post-Gazette was contacted by Colon's agent, Joe Linta. If accurate, it would likely land Colon on the IR, ending his season. 

Colon missed all of the 2010 season after rupturing an Achilles tendon in spring practice. The Steelers starter in Super Bowl XLIII, Colon will have now played one game since helping to defeat the Cardinals for the league championship in February, 2009. 

He signed a five-year, $29 million contract this off-season, and played in the Week 1 loss at Baltimore.
