Indianapolis Colts offensive lineman Joe Reitz has been ruled out for today’s contest against the Baltimore Ravens due to a concussion, while safety Tom Zbikowski and offensive lineman Winston Justice are among those questionable to play.

Reitz hasn’t been able to practice all week due to his concussion. He is expected to be replaced by Jeff Linkenbach.

Zbikowski, the former Raven, was limited at practice Wednesday due to his knee injury. However, the safety was able to return at full capacity on Thursday and Friday. Justice (shoulder) followed the same path at practice this week and is also considered questionable to play.

Beyond Zbikowski and Justice, running back Delone Carter (ankle), defensive lineman Antonio Johnson (ankle) and offensive lineman A.Q. Shipley (knee) are also listed as questionable.

Everyone else on the Colts’ injury report is probable to play, including starters Pat Angerer (illness), Andrew Luck (knee), Cory Redding (quad) and Samson Satele (ankle).
