ST. LOUIS - Carl Gunnarsson sustained a lower-body injury in Thursday's 4-3 shootout loss to the Vancouver Canucks.
Blues Head Coach Craig Berube said Gunnarsson is considered day-to-day.
"We'll see how he is tomorrow," Berube said.
Gunnarsson had 14 minutes and 30 seconds of ice time against the Canucks. In five appearances this season, he has one assist.
