Suzuki tied it 1-1 on a power play 24 seconds into the third, scoring on a wrist shot from the top of the right face-off circle to extend his goal streak to four games.
Gallagher scored 27 seconds later to put Montreal up 2-1. He knocked down Guhle’s shot from the left point and lunged to his right to swipe the puck around Swayman.
“I think the first minute of the third was a microcosm of the first two periods,” Bruins coach Jim Montgomery said. “We were lucky to be in the position we were in up 1-0. I think that’s Swayman that gets us the point.”
The Bruins had a goal by Oskar Steen disallowed at 2:05 after Montreal successfully challenged that the Boston forward had interfered with Montembeault on the play.
“I think they played hard, you’ve got to tip your cap to them,” Swayman said. “They came out in the third knowing that they needed a lead and they played a great third period. So, I’m really happy with our response. It’s a team effort, we couldn’t have got to overtime without the boys in front of me, so I’m happy with that, but we want to execute all the way through and finish games out.”
