Tyler Seguin scored the only goal in a shootout as the Bruins defeated the Canadiens, 4-3, Wednesday night at Bell Centre.

The Bruins blew a two-goal lead in the third period, surrendering goals to Max Pacioretty and Erik Cole to tie the game after the B’s had led, 3-1. They had only two shots on goal in the second period, but bounced back with a strong effort in overtime before Tim Thomas blanked the Habs in the shootout. Thomas is now a perfect 5-0 in shootouts this season.

The Bruins first got on the board with Andrew Ference’s fifth goal of the season, which set a new career high for the veteran defenseman. Mathieu Darche tied the game for the Habs with a shorthanded goal early in the second period, but masterful work from Benoit Pouliot on Chris Campoli gave the B’s the lead back. Patrice Bergeron added to the lead with a power-play goal.

Brad Marchand could be getting a call from NHL disciplinarian Brendan Shanahan, as the 23-year-old winger clipped Habs defenseman Alexei Emelin at the end of the second period. Marchand was suspended for five games last month for clipping Canucks defenseman Sami Salo.

Marchand almost ended the game in overtime, beating Carey Price with a wrist shot that rang off the crossbar and into the stands with 2:19 remaining.

There were a whopping four goaltender interference penalties called in the first two periods. Pacioretty went off in the first period for contact with Tim Thomas, and the second period featured matching goaltender interference calls on Louis Leblanc and Daniel Paille. Forty-seven seconds later, Cole was called for the same infraction, leading to Bergeron’s power-play goal.

WHAT WENT RIGHT FOR THE BRUINS

- Ference set a new career high with his fifth goal of the season, though with 21 points at this point, he still has a ways to go to match his career best points total of 31, which he registered in the 2005-06 season with the Flames.

Ference nearly added his sixth of the season with just over five minutes left in regulation, but his shot rang off the post. With Bruins’ defensemen’s contracts coming into focus given the extension the B’s gave to Johnny Boychuk Tuesday, Ference sure is a bargain at $2.25 million a year.

- Tyler Seguin picked up the primary helper on Bergeron’s tough-angle goal, giving Seguin his first point in his last four games, and second point in his last eight games. Seguin had four shots on goal for the B’s, though he had a bad turnover in the second period on which Tim Thomas bailed him out. The B’s are obviously looking for more production from the second-year player, though it may have been unrealistic to expect him to maintain the torrid pace on which he began the season.

WHAT WENT WRONG FOR THE BRUINS

- The Bell Centre crowd was pretty classless in the seconds that followed a pretty scary play for the Bruins. With just seconds remaining in the first period, Tomas Plekanec tried clearing the puck out of the Habs’ zone but hit Zdeno Chara in the face with the puck. The Bruins’ captain fell to the ice, bloodied, before heading straight off and down the tunnel. Though Plekanec immediately went to check on Chara, while the Bell Centre crowd cheered. Luckily for the Bruins, Chara was alright after getting stitches and returned at the start of the second period.

- Speaking of Chara, the Bruins’ captain was on the ice for all three of the Canadiens’ goals. He committed an especially uncharacteristic turnover prior to the Habs’ third goal, as a lazy pass in the Bruins’ zone was intercepted by Cole, who beat Thomas to tie the game.

- Wednesday’s game marked Thomas’s fourth consecutive game in which he allowed three or more goals. That matches Thomas’ longest such streak from last season. The current rough stretch for Thomas dates back to last Wednesday, when he allowed three goals in relief of Tuukka Rask in Buffalo.

- Rich Peverley left the game late and did not return. If he is injured, Peter Chiarelli’s job just got a little tougher.

- Darche’s shorthanded goal was the first that the Bruins had allowed this season. Until the second-period goal, the B’s were the only team left in the NHL that had not allowed a shorthanded tally.
