MONTREAL -- Alex Galchenyuk stayed hot, but his streak turned out to be a second thought in the aftermath of the Montreal Canadiens' 3-2 win against the Buffalo Sabres on Thursday.

All-Star defenseman P.K. Subban was stretchered off the ice with 2:26 remaining in the third period after falling awkwardly in battle in the corner with Buffalo's Marcus Foligno and a subsequent collision in which teammate Alexei Emelin's behind caught him in the head.

"When you see that whole situation, it's really scary," said Canadiens captain Max Pacioretty. "To see that many trainers on the ice and doctors, it's tough to play after that."

The Canadiens had taken the lead a few minutes earlier when Torrey Mitchell potted a rebound of a Mark Barberio shot to restore a Montreal lead.

"You're trying to win a hockey game but you almost feel like you don't want to keep playing at that point in time," Sabres coach Dan Bylsma said. "There's a couple of minutes left in the game but you're really mostly, entirely, concerned for the athlete and for the person. The game's an afterthought."

Galchenyuk scored a pair for Montreal (32-30-6), becoming the first Canadiens player with five multi-goal efforts in an eight-game span since Jean Beliveau in 1959, per Elias Sports Bureau.

Nicolas Deslauriers and Brian Gionta connected for the Sabres (27-33-9).

Mike Condon made 36 saves for the Canadiens while Robin Lehner stopped 31 shots for the Sabres.

Deslauriers' fifth of the season broke the scoreless tie at 9:00 of the second period. Jake McCabe picked up Zach Bogosian's deflected shot attempt along the left side and fired a shot from outside the circle that hit Deslauriers before beating Condon glove side.

The goal announcement had barely begun when Galchenyuk tied the game 1-1 a mere nine seconds later. Mark Barberio dumped the puck in after the center ice faceoff and it rimmed around behind the net to Lehner's right. Pacioretty got to it first and found his center just below the hashmarks, who quickly buried it.

After struggling to generate much on its first two power plays, Montreal finally cashed in late in the frame. Subban dove to keep the puck in along the boards and Sven Andrighetto sent the loose puck over to an uncovered Galchenyuk in front of the net, connecting for his third straight multi-goal game and team-leading 25th tally of the season at 19:16.

"It's great to see," said Barberio, who picked up a pair of assists on the night. He's playing with a lot of confidence and it seems like every time he touches the puck, it ends up in the net. It's fun to watch him.

Gionta made it 2-2 at 5:10 of the third period. Evander Kane tossed a shot toward the net from the left circle, sending it past Condon off an unattended Gionta's skate in front.

"We played pretty hard," Foligno said. "We would have liked to have a little more offensive zone time. There was a lot of neutral zone and back-and-forth. For our line, I thought we played well. It was a tough battle. "
