Jakub Dobes allowed five goals on 13 shots in the first two periods for Montreal (10-5-2), which is 1-2-2 in its past five games. Sam Montembeault made four saves on six shots in the third.
“You don’t want too much concern to creep in, but we’ve got to clean things up and get back to the basics of what makes our team successful,” Canadiens captain Nick Suzuki said. “And that’s playing with the puck, forechecking, being a hungry team and an aggressive team, and I think recently we’ve backed off the aggressiveness and just kind of been sitting back a little bit too much defensively.”
Canadiens forward Alex Newhook had to be helped off the ice at 4:10 of the second period after he crashed feet first into the end boards. There was no update on his status after the game.
“It was really tough,” Montreal forward Brendan Gallagher said. “Obviously, we’re going to be without ‘Newy’ for a little bit here, a player that worked really hard in the offseason and knew how important the season was to him and our team. He was having an unbelievable year and you just feel for him at this point.”
Wyatt Johnston’s power-play goal at 14:21 of the first period gave the Stars a 1-0 lead. He was in the bumper position to one-time a feed from Roope Hintz for his 100th NHL goal.
Esa Lindell made it 2-0 at 3:50 of the second with a wrist shot stick side on Dobes from the left side of the slot off a pass from Miro Heiskanen.
Tyler Seguin pushed the lead to 3-0 at 7:10 when he scored on a breakaway. Seguin drove in alone and put a snap shot past Dobes glove side after he got behind the defense and accepted Robertson’s stretch pass from Dallas' defensive zone.
“It’s one of those that you just hope it gets to him,” Robertson said.
Robertson put the Stars up 4-0 at 15:10. He cut across the goalmouth, received a pass from Thomas Harley and lifted a backhand over Dobes.
