BOSTON -- Brad Marchand scored 2:06 into overtime, and the Boston Bruins defeated the Montreal Canadiens 2-1 at TD Garden on Saturday.
Marchand started along the left wall and circled the net before scoring with a wrist shot from the right hash marks.
"Yeah, got a little lucky," Marchand said. "I think they were a little tired. They were definitely a little bit [tired], so nice to get the win though."

The Canadiens were playing the second half of a back-to-back and were without Max Pacioretty (lower body) and defenseman Victor Mete (hand).
"I'm not going to complain about our guys' effort," Montreal coach Claude Julien said. "You know, it's our fourth game in six nights and we've been traveling, and we know the circumstances from [Friday] as well. We tried to hang in there and we played a really good hockey club first and foremost.
"At the same time, our goaltender, who was fresh from not playing last night, was giving us that opportunity. When you take six penalties, whether they're deserved or whatever the case may be, it eventually catches up to you and we did our best and eventually the fresher team and the better team won."
Gallagher scored at 9:16 of the first period to give the Canadiens a 1-0 lead. After he stole Kevan Miller's pass in the neutral zone, Gallagher skated in and beat Khudobin blocker side with a wrist shot from the high slot.
DeBrusk tied it with a power-play goal at 17:15 of the third period after he redirected Nick Holden's slap pass past Niemi.
"A guy [Montreal's Nicolas Deslauriers] lost his stick. I think that's a key part of it," Krug said. "No, I mean, it can be frustrating, you have so much time on the power play, you're not getting the goals. We had a lot of good looks. Ultimately it was just getting a shot into the slot and those guys do the work. Great job by those guys to stick with it."

Rookie defenseman Charlie McAvoy, who is second on the Bruins with an average of 22:29 of ice time, left in the first period with a lower-body injury.
"Yeah, it's never easy for sure," Miller said. "You want to make sure obviously that the guy who went down is OK, but you just have to manage your minutes and we've got a good group back there. You kind of pick each other up, so it was good tonight."

They said it
"When we talk about our roster, and we've got a lot of young guys in there and they're battling and we're finding ways to get points, I think we're growing as a team. And we still have a long ways to go, but at least we're going in the right direction." -- Canadiens coach Claude Julien
"We were talking about that in the room. [Assistant coach] Kevin [Dean] said that pound for pound he must be the strongest guy on the puck." -- Bruins coach Bruce Cassidy on forward Brad Marchand
