CANADIENS 7, SABRES 5: Cole Caufield scored twice, including the game-winner, to lead Montreal in Buffalo. The win snapped a six-game losing streak for the Canadiens, and ended a three-game winning streak for the Sabres. Caufield’s two goals put him at a league-leading 12 for the season. His second was a power-play goal with 7:02 left in the third period that put the Canadiens ahead to stay. Buffalo leading-scorer Tage Thompson and defenseman Mattias Samuelsson exited the game with lower-body injuries and did not return.
