Blues forward Dallas Drake could miss Game 5 of the first-round playoff series against the Blackhawks tonight after injuring himself making a first-period check in Game 4.

Drake did not participate in the Blues' optional skate on Wednesday, a day after St. Louis' 1-0 victory in Chicago. He was hurt after making a big open-ice hit on Kyle Calder at 6:18 of the first period.

Calder's stick apparently struck Drake in the face after the hit and both players crashed to the ice. A dazed Drake was helped from the ice, collapsing once on his way off.
