Steelers coach Mike Tomlin confirmed the team's starting left guard underwent knee surgery Monday and will miss several games, according to Ed Bouchette of the Pittsburgh Tribune-Review.
The musical chairs game continues in Pittsburgh. We mentioned Monday that Colon's injury would likely trigger All-Pro Maurkice Pouncey's move from center to guard, with Doug Legursky taking over the middle position. That might not be the plan.
The Steelers can't afford any more injuries up front. Their season might depend on the health of their remaining linemen.
