Remember when Carlo Colaiacovo got leveled by Jordin Tootoo and looked like he was in the land of hazy thoughts—the same place Cam Janssen took a trip to against Philly? Well the diagnosis, nearly a week later, is confirmed. Cola has a concussion and has been placed on injured reserved. Nathan Oystrick, who played Saturday against the Thrashers and wasn't bad—he had an assist and a nice hit is being recalled he. He was sent down after Saturday's game but will be back up before the Blues take on San Jose tomorrow. With Nikita Nikitin still not ready, the Blues needed a sixth d-man. Enter Oystrick.
