NFL Network's Jason La Canfora reports that Steelers RT Willie Colon expects to undergo season-ending Achilles' surgery on Wednesday.
Colon is the Steelers' best lineman, so this is a very tough loss for Rashard Mendenhall, immobile fill-in QB Byron Leftwich, and Ben Roethlisberger once he returns from suspension. Pittsburgh's most likely Week 1 front-five lineup now probably would have Trai Essex moving from guard to right tackle, Max Starks staying on the left side, and Maurkice Pouncey, Justin Hartwig, and Chris Kemoeatu on the interior. What once appeared to be a revamped and potentially promising group for 2010 has taken a significant blow.
Huge loss for an already shaky line. I personally just downgraded all skill players on Pittsburgh.
