The Blues (46-20-10) got the best of the Bruins (46-24-5) last Tuesday, doubling them on the scoreboard thanks to a 4-2 win.
The Blues are on fire as of late, having gone undefeated in their last nine games to move up to second place in the Central Division. As for the B's, they're looking to build off a clutch 2-1 win over the Penguins on Saturday to try and catch up to the third seed Tampa Bay Lightning in the Atlantic Division.
Once again, the Bruins will be turning to rookie goaltender Jeremy Swayman (21-12-3) between the pipes tonight, as Linus Ullmark is still out nursing an injury. Swayman will be backed up by Troy Grosenick against the Blues.
Aside from Ullmark, other notable scratches include stars David Pastrnak and Hampus Lindholm, while Josh Brown, Jack Studnicka and Anton Blidh will also sit this one out.

Taylor Hall � Erik Haula � Curtis Lazar
Trent Frederic � Charlie Coyle � Craig Smith
Nick Foligno � Tomas Nosek � Marc McLaughlin
