MONTREAL -- A video review left Bruins coach Bruce Cassidy seeing red.
An overturned goal on a coach's challenge for offside in the third period gave Montreal momentum, and the Canadiens went on to beat Boston 5-4 on Tuesday -- a rare regulation loss for the division-leading Bruins.
It looked as if Cassidy's team went up 5-4 when Charlie Coyle beat Carey Price. But the officials held a lengthy video review on Claude Julien's challenge and determined Coyle was offside on the zone entry during the play.
"The rule was put in place specifically for egregious (calls)," Cassidy said. "They're over there for three minutes. What is the purpose for this rule? You either find something or you don't. Now you're looking for something for it to be offside. You know it's going to go the other way and it did.
"It was a big part of the game and it didn't go our way."
Down 4-3 in the third, the Bruins tied the score when Sean Kuraly surprised Price on a wraparound at 3:03. It looked as if Boston was taking over -- until Coyle's goal was overturned.
Ben Chariot scored and gave Montreal (8-5-2) the win with a wrist shot from the face-off circle just a few minutes later. The Canadiens have won four of their last five.
"Our video guys saw the puck on the line and the skates across it," said Julien, who coached his 1,200th NHL game. "If we don't win that challenge, they have a one-goal lead and a two-minute power play. It could have gone their way.
"We were right and we stopped Boston's momentum. From there, we got better."
The Bruins (11-2-2) saw their six-game win streak come to an end as they lost in regulation for the first time since Oct. 10, in Colorado against the Avalanche.
Boston was playing the second game of a back-to-back and it showed, going down 3-1 in the first period.
David Pastrnak netted the equalizer six seconds into a Boston power play, a one-timer at 14:55. Pastrnak, the NHL scoring leader, extended his career-high point streak to 13 games.
It was hardly a goaltending battle, with Price stopping 21 of 25 shots, while Rask gave up five goals on 31 shots.
"It's one of those nights where instead of a hockey puck, it feels like a golf ball out there," said Rask, who suffered his first regulation defeat. "I was just not tracking it well. Tough night for me. Couldn't really make a save."
The Canadiens failed to clear their zone and Clifton made them pay with his first NHL goal at 7:17 to make it 3-2.
Boston evened the score at 18:13 when Bjork was first to a loose puck in the crease. Mete gave Montreal the 4-3 lead 42 seconds later with a shot from the point.
Bruins captain Zdeno Chara played his 1,500th game. Bell Centre fans gave Chara, who is usually booed in Montreal, a rare ovation for the accomplishment. The 42-year-old is the 21st player to reach that mark.
"I really appreciated it and it was very classy," Chara said of the fan reaction. "It's something I will definitely remember. That just shows they are very passionate fans. We had some battles, it's a good rivalry. Lots of history with both teams. Always fun to play these games."
Bruins: At Detroit Red Wings on Friday.
Canadiens: At Philadelphia Flyers on Thursday.
