Steelers offensive tackle Willie Colon has suffered a torn Achilles, a league source told ESPN's Adam Schefter. Colon will have more tests to confirm the injury on Tuesday, but if initial reports are true he'll miss the 2010 season. "It looks like it's an Achilles [injury]," Colon's agent Joe Linta said. "We want to wait to confirm it, but that's kind of our worst fears."
