The skinny: Francis Bouillon scored his first goal of the season at 1:26 of overtime to give the Canadiens an improbable 5-4 win over the Ottawa Senators Saturday night at the Bell Centre. The Canadiens fell behind 4-1 on Clarke MacArthur’s goal at 5:08 of the third period, but they scored three goals in the final 3:22 of regulation to send the game into overtime. Lars Eller started the comeback at 16:38 with his first goal since Jan. 2. Brian Gionta made it 4-3 at 17:56 and David Desharnais tied the game with a power-play goal with 0.3 seconds remaining in regulation. Where they stand: The Canadiens have 79 points and are one point behind idle Toronto in the battle for second place in the Atlantic Division. Tampa Bay also has 79 points and has the edge on Montreal because it has played one fewer game. Price in and out: Carey Price played for the first time since he won a gold medal with Team Canada at the Sochi Olympics and he stopped 30 of 34 shots for the win. Coach Michel Therrien said he was pleased with the goalie’s performance and he’s giving Price a day off Sunday. The goalie remained in Montreal while his teammates flew to Buffalo to face the Sabres. P.K. shows poise, patience: Defenceman P.K. Subban had three assists, including one on Desharnais’s tying goal. Said Subban: “I almost missed the pass (from Markov) because I was looking up at the clock. Davey had one hand on his stick and was waving at me to shoot the puck but there were a lot of people in front and I thought that if I did shoot, it would get blocked. I saw (Desharnais) at the side of the net and I hoped he had time to shoot.” Bouillon in a pinch: “It’s probably the most important goal of my career,” said Bouillon, who pinched in after Robin Lehner made a stop on Andrei Markov. “In overtime, you try to create some offence and I saw the puck lying there in front.” Wasted opportunities: The Canadiens grabbed a 1-0 lead when Daniel Brière took the puck away from Bobby Ryan at the blue line and scored at the 38-second mark of the first period. The Canadiens dominated the period but they had trouble finishing and Jason Spezza scored a tying goal at 3:08. The Canadiens had the only three power plays in the period and they wasted some opportunities. Brière had two chances on one shift but Robin Lehner made a skate save on his first try and Brière fired wide on his next attempt. Senators come on: In the second period, the Canadiens paid the price for letting the Senators stick around. Montreal received a break when a video replay wiped out an apparent goal by Colin Greening, who crashed into Price after being tripped by Lars Eller. The replay showed that the net came off its mooring before the puck crossed the goal line. The Canadiens killed off the penalty to Eller but they were caught sleeping seconds later when Zack Smith took a stretch pass from Erik Karlsson and scored on a breakaway at 17:10 for a 2-1 Ottawa lead. Ales Hemsky and MacArthur made it 4-1 in the third period.
