Blues forward Cam Janssen is expected to miss at least two weeks with a concussion. He has been placed on injured reserve and will be re-evaluated at that time.
Blues Head Coach Davis Payne shared the news with the media on Sunday morning after a team practice at the Ice Zone at St. Louis Mills.
Janssen left Saturday's game in the second period after a collision near the Blues' bench. He did not return to the game.
The Blues earned a 2-1 overtime win on Saturday against the Philadelphia Flyers.
