Schneider returns to the Vancouver lineup after watching the past four games from the bench as Roberto Luongo's backup. The Canucks went 2-2 in that span and surrendered first place in the Northwest Division to the Minnesota Wild.
Schneider was ticketed as Vancouver's starting goaltender this season after he displaced Luongo in the No. 1 role during last spring's Stanley Cup playoffs.
But the Canucks did not trade Luongo as expected in the off-season, and the two goaltenders have shared the duties in the lockout-shortened season.
Meanwhile, winger Zack Kassian will return to the lineup after sitting out losses against Detroit and Minnesota with a sore back.
Rookie goaltender Jake Allen will make his fourth-straight start for the Blues. St. Louis is riding a three-game win streak with Allen, who has split this season between the minors and the NHL.
