Robert Thomas will not play against the Minnesota Wild on Saturday as he deals with an upper-body injury.
Blues Head Coach Craig Berube said Thomas is considered week-to-week.
Thomas was injured after being hit into the boards Friday by Wild defenseman Carson Soucy in the third period of a 9-1 Blues' win. Thomas was attended to by Head Athletic Trainer Ray Barile and skated off to the locker room on his own.
Thomas played 12 minutes and 39 seconds in Friday's game, recording two assists.
