MONTREAL --Brandon Sutter scored 52 seconds into overtime tonight to give the Penguins a 7-6 victory against Montreal at the Bell Centre.
Sutter beat Montreal goalie Carey Price with a wrist shot from the right hash mark for his second of the game.
The Penguins were without defenseman Paul Martin, who has not played since the second period of their 4-1 loss Thursday at Carolina.
Coach Dan Bylsma did not, however, rule out Martin returning when the Penguins face Tampa Bay at Consol Energy Center at 7:38 p.m. Monday.
"I don't have what the probability is," Bylsma said. "He'll possibly skate tomorrow or the next day. We'll see."
Martin's spot was taken by Mark Eaton, who made his first appearance since signing on Feb. 25 with the Penguins as a free agent.
Left winger Brandon Prust put Montreal in front, 1-0, at 5:41 of the opening period, when he knocked in a Tomas Kaberle rebound from the front lip of the crease.
That was just the second time in 13 road games the Penguins have given up the first goal.
The Penguins pulled even during a power play with 52.5 seconds left in the period, as a Kris Letang pass hit the skate of Montreal defenseman Alexei Emelin and went directly to Sutter, who threw it into a mostly open net for his fifth of the season.
Montreal went back in front at 4:14 of the second, when Brendan Gallagher took the puck to the net and, after Tomas Vokoun stopped him, Max Pacioretty swooped in to backhand the rebound into the net.
The Penguins, though, responded by scoring twice in 31 seconds to grab the lead.
Chris Kunitz banked a shot off Canadiens goalie Price and into the net from behind the goal line at 7:58 for his tenth of the season, and Matt Cooke made it 3-2 with a shot from near the top of the left circle at 8:29.
Cooke struck again at 13:05, beating Price from the slot for his fifth of the season, but Montreal countered with a Brian Gionta deflection at 17:37, four seconds after a holding minor to Tyler Kennedy of the Penguins had expired.
The Canadiens then tied the game, 4-4, as P.K. Subban beat Vokoun from the left side of the crease with seven-tenths of a second to go before the intermission.
Montreal reclaimed the lead at 5:25 of the third, as David Desharnais collected a Gallagher rebound and tucked it inside the right post, but Kunitz beat Price from the slot at 8:33 to revive the Penguins.
Sidney Crosby gave the Penguins a short-lived lead when he put in a Letang rebound from the inner edge of the left circle at 10:24, but precisely a half-minute later, Gionta beat Vokoun on the short side with a slap shot from the right point to make it 6-6.
