Alex Galchenyuk scored at 3:37 of overtime, and the NHL-leading Montreal Canadiens beat the Detroit Red Wings 2-1 on Saturday night.
Brendan Gallagher also scored for Montreal, which improved to 16-4-2. Carey Price stopped 32 shots.
Justin Abdelkader scored for Detroit (10-11-1), and Petr Mrazek made 22 saves.
Galchenyuk finished off a 2-on-1 by one-timing a pass from Alexander Radulov past Mrazek from the bottom of the left circle. It was Galchenyuk's ninth goal.
Gallagher tied it at 1 with 8:05 left in the third period when he tipped in a shot by Tomas Plekanec. It was Gallagher's first goal in 16 games and No. 5 on the season.
Abdelkader got the game's first goal 3:20 into the third period. He beat Price high on the glove side with a wrist shot from the high slot that deflected off the stick of Canadiens defenceman Greg Pateryn. It was Abdelkader's fourth goal.
Two Red Wings were helped to the dressing room in the second period and neither returned.
Defenceman Brendan Smith got his legs tangled up with Montreal's Phillip Danault along the boards in the Detroit zone and limped off with 8:01 left.
Forward Tyler Bertuzzi made it off the ice by himself, but on one leg, with 3:13 remaining after a low hit in the corner along the boards from Montreal defenceman Alexei Emelin.
Price made a nice save on a tip by Luke Glendening in the middle of the second.
Mrazek made a spectacular glove save on Arturi Lehkonen at 5:01. Lehkonen, stationed to the right of the net, one-timed a cross-crease pass, but Mrazek reached across and caught it.
The Canadiens outshot the Red Wings 10-5 in a scoreless first period.
