Center was injured Saturday against Rangers;
left wing has missed four games with elbow injury
The Blues have placed Jori Lehtera on injured-reserve after the center sustained an upper-body injury Saturday against the New York Rangers.
Blues coach Ken Hitchcock said Monday that there was a chance Lehtera would join the team in the latter portion of the three-game trip but would not join them initially.
The Blues are home next week for three games.
The move to put Lehtera on IR is a good indication the Blues are about to activate left wing Jaden Schwartz, who's missed the first four games with a hyperextended left elbow sustained in practice on Sept. 29.
Schwartz accompanied the Blues on their three-game Western Canada swing and is likely to return Thursday against the Edmonton Oilers.
Center Kyle Brodziak and defenseman Carl Gunnarsson, who also left Saturday's 3-2 victory with upper-body injuries, accompanied the team and continue to be day-to-day. Both missed Tuesday's 2-1 overtime loss to the Vancouver Canucks.
