The 35-year-old Steen was injured on Wednesday versus the Edmonton Oilers. He's been placed on injured reserve and will be re-evaluated in December.
The Blues' forward depth will now be put to the test. Vladimir Tarasenko is already out for at least five months after undergoing shoulder surgery in October.
Steen has posted five assists in 17 games this season.
Grubauer is expected to miss at least Thursday and Saturday's games but will accompany the team when it embarks on a five-game road trip Nov. 12, according to The Athletic's Ryan Clark.
Jordan Binnington may have helped the St. Louis Blues take home the Stanley Cup last season, but he believes he should have taken home the Calder Trophy too.
"There's a little bit of that bad taste in my mouth about the outcome last year," Binnington said after beating the Vancouver Canucks Tuesday, according to the St. Louis Post-Dispatch's Jim Thomas. "But he's (Elias Pettersson) a talented player, so it's good going up against some of the best."
Binnington finished second in voting for the Rookie of the Year award, losing out to Pettersson. The Blues goalie earned 18 first-place votes to the Canucks star's 151.
"Yeah," Binnington added when asked if he thinks he deserved to win the honor. "(But) they’ve got a good young team and some elite talent. He’s one of those guys, so it’s a lot of fun."
The two players aren't showing signs of slowing down in their sophomore seasons. Binnington sports an 8-2-3 record paired with a .921 save percentage and 2.43 GAA. Pettersson has six goals and 20 points in 15 games.
Mike Babcock might not have been too impressed with his Toronto Maple Leafs after they squeezed out two points against the lowly Los Angeles Kings on Tuesday, but he saw the game as a stepping stone.
"We need to go through that," the head coach said postgame, according to Yahoo Sports' Justin Cuthbert. "We need to figure out who we are, and the harder the game is for us the better it is.
"Would you like to win by a touchdown and everyone relaxes and all that? Yeah, but we're not getting anywhere like that. This is important to do."
The Leafs mustered just 23 shots on goal and were tied with the Kings late until Auston Matthews and William Nylander scored back-to-back markers midway through the third period to seal the victory.
"You give up one goal, you play well without the puck, goalie makes some saves, we didn't win it on special teams, we had to grind. It was good for us," Babcock added.
The Leafs will face a stiffer test at home on Thursday when they take on the Vegas Golden Knights.
Despite the Calgary Flames' 4-3 overtime victory over the Arizona Coyotes on Tuesday, head coach Bill Peters wasn't happy with his team's performance.
"We gotta start playing for each other and playing the right way," Peters said postgame. "I don't think we're doing that right now. I don't see that. If we are, I'm missing it a little bit."
Peters didn't shy away from calling out certain players, either.
"You've got guys skating in mud, and (Mark Giordano) is skating in mud, and (Elias Lindholm) is skating in mud, and you're relying on these guys to come back, too, and they're gassed.
"We need more out of some veteran guys."
The Flames gave up several high-quality scoring chances to the Coyotes and trailed by two with less than four minutes to play in regulation. They eventually evened the score before Matthew Tkachuk buried the overtime winner.
Calgary currently sits fifth in the competitive Pacific Division with a 9-7-2 record but is just two points behind the first-place Edmonton Oilers.
The Boston Bruins and Edmonton Oilers are first in their respective divisions largely because of these players, but which pair holds the edge?

The Bruins have cruised to six straight wins while earning points in their last 10 games, and they've lost just once in regulation this season. Much of their success can be attributed to first-line juggernauts Pastrnak and Marchand, with help from their center Patrice Bergeron.
Through 14 contests, Marchand has recorded two five-point games, and he's riding a career-best 13-game point streak. Pastrnak has also been terrorizing opponents, and he leads the league in goals and points.

The Boston wingers' underlying numbers show how dominant they've been to start this season. Averaging just under 20 minutes per game, the two have been driving play in the offensive zone and rank among the top forwards in Corsi For Percentage.
They help generate offense from all over the zone when on the ice.

Marchand and Pastrnak have combined for 24 markers, which accounts for 46 percent of the Bruins' goals this season.

After McDavid and Draisaitl were responsible for 40 percent of Edmonton's goals last season, linemate James Neal has supported them early this campaign with his secondary scoring. The high-octane duo is still off to a scorching start, even if the underlying numbers aren't as flashy.
Their time on ice is the stat that jumps out. Among all forwards, McDavid and Draisaitl rank first and second in ice time, averaging just under 24 minutes per night. The two are playing hard minutes in Edmonton, and they start shifts and play in the defensive zone more often than last year.

McDavid continues to drive play at a high rate when in the offensive zone, creating lots of scoring chances from high-danger zones. Draisaitl, meanwhile, has had less of an isolated impact in the offensive zone than his linemate so far this season.

The pair have combined for 20 goals this year, which is 44 percent of the Oilers' total. With linemate Neal's 11 goals included, the line has notched 69 percent of the team's tallies.
Bottom line
The Bruins duo holds the edge early this season due to its better production. Pastrnak and Marchand may enjoy the luxury of playing with one of the league's best two-way centers in Bergeron, but we shouldn't penalize them for that.
With tons of hockey left to be played, it'll be a treat to watch these four superstars duke it out at the top of leaderboards.
Quinn Hughesannounced he will make his return to the Vancouver Canucks lineup on Tuesday versus the St. Louis Blues after missing one game with a knee injury.
"Green light, good to go," Hughes said Tuesday. "A lot of people thought it was my ankle ... I just kind of bruised my knee a bit."
Hughes left Friday's contest against the Anaheim Ducks and didn't return after awkwardly twisting his leg when his skate got caught in the ice.
The rookie defenseman has 10 points in 13 games so far this season and has been in the discussion for the Calder Trophy.
Poehling, who scored a hat trick and shootout winner in his NHL debut last year in Montreal's regular-season finale, has three goals and five points in 13 games with the Canadiens' AHL affiliate this year.
Kotkaniemi, the third overall pick of the 2018 NHL Draft, missed Saturday's contest against the Dallas Stars with a groin injury. The Finnish sophomore has two goals and one assist in 12 games this season.

Malkin - who's missed the Penguins' last 11 games with a leg injury - is likely to make his return to the lineup Saturday against the Edmonton Oilers.
"He looks good. He's participating in practice in a full capacity," head coach Mike Sullivan said earlier Friday. "We will see how he responds after today's practice, but it's certainly encouraging (for him to play tomorrow)."
The 33-year-old was hurt in the Penguins' second game of the season Oct. 5 and was expected to miss at least a month. Pittsburgh has weathered the storm during his absence, compiling a 7-4-0 record over that span.
Malkin has one goal in the two games he's appeared in this season.
