Tage Thompson and Rasmus Dahlin each had a goal and an assist, and Alex Lyon made 31 saves for Buffalo, the No. 1 seed in the Atlantic.
Montreal leads the best-of-7 series 2-1. Game 4 is back at Bell Centre on Tuesday (7 p.m. ET; ESPN, SN, CBC, TVAS).
“They’re a skilled team,” Thompson said. “They’ve got a lot of players that can make plays and score. They don’t need a whole lot to put it in the back of the net. I think we’ve been opening it up a little bit too much, taking a bit too many risks off the rush. Obviously, we like when our 'D' are joining and getting involved in the play, but we’ve got to be smart when we do it, pick our times, and the forwards have got to be better when they are in there and tracking back.”
Thompson put the Sabres up 1-0 when he scored 53 seconds into the first period. Dahlin’s shot from the point caromed off the end boards, hitting Canadiens defenseman Alexandre Carrier’s right leg and changing direction before Thompson put away the rebound in front.
Newhook tied it 1-1 at 15:31 with his first goal of the game. After battling with Buffalo defenseman Bowen Byram for possession behind the net, Newhook came out front to put away the rebound of Evans’ shot, which hit off the stick of Sabres defenseman Conor Timmins and past Lyon.
Caufield put Montreal up 2-1 with a power-play goal at 6:05 of the second period. After his tap-in opportunity went wide of the left post in the opening minute of the period, Caufield made no mistake on another chance at an open net when Hutson set him up in front for the snap shot past Lyon glove side.
“I’m just trying to build off these last couple of games,” Caufield said. “Obviously it’s tight out there, there’s little room, but when there is, you’ve got to take advantage of that. And I think I’m starting to do that, and hopefully we can keep that going.”
