The game: Boston beat the Canucks 8-1 as the Stanley Cup Finals get nasty.

The series: Vancouver still lead the series 2-1.

The lowdown: Shortly after the Boston Bruins lost Nathan Horton to a frightening injury, they found a dazzling offensive rhythm that got them back into the Stanley Cup finals.

Andrew Ference and David Krejci each had a goal and an assist during Boston’s four-goal second period, Tim Thomas made 40 saves, and the Bruins beat the Canucks 8-1 in Game 3 on Monday night, trimming Vancouver’s series lead to 2-1.

Mark Recchi scored two goals for the Bruins, who turned a big win into a blowout with four more goals in the final 8½ minutes of the third period against beleaguered goalie Roberto Luongo, who won the first two games of the series in Vancouver.

The Bruins were one goal shy of equaling the finals record of nine in a game, set by Detroit in Game 2 of the 1936 series and matched by Toronto six years later in Game 5. The eight goals were the most scored in the finals since Colorado topped Florida 8-1 on June 6, 1996, in Game 2, according to STATS LLC.

Boston emerged from its offensive slump after Horton was taken off the ice on a stretcher in the first period after taking a late hit to the head from Vancouver defenseman Aaron Rome.

“It’s always tough when a guy goes down,” said forward Brad Marchand, who scored a short-handed goal. “We really wanted to get this win tonight for him. It’s a very tough situation, and everyone is worried about him, but it definitely gave us motivation to win.”

Game 4 is tomorrow night in Boston.

The palpable excitement of Boston’s first home finals game in 21 years turned into unease just 5 minutes into Game 3.

After Horton passed the puck to Milan Lucic at the Vancouver blue line, Rome left his feet to deliver a hard shoulder check to Horton’s upper chest and head. Horton appeared to be unconscious after he landed flat on his back, his arm spookily reaching up into empty space.

Medical personnel spent several minutes attending to Horton, who scored the Bruins’ winning Game 7 goals in the first round against Montreal and again in the Eastern Conference finals against Tampa Bay. The crowd gave a standing ovation as Horton was wheeled off the ice, wearing a neck brace and apparently talking.

Rome got a five-minute major for interference and a game misconduct, with at least one fan throwing a yellow towel at the Vancouver bench while Rome went to the dressing room. The shaken Bruins didn’t score on six shots on their marathon power play, with the Canucks blocking shots and diving to protect Luongo.

The Boston crowd rose and cheered several minutes later when a scoreboard message told them Horton could move his arms and legs when he was taken to Massachusetts General Hospital.

Boston fans already were upset with the Canucks after two bad-tempered games in Vancouver, including Alex Burrows’ apparent bite on Patrice Bergeron’s finger during Game 1. The bite was still on the minds of both teams, with players from both teams taunting their opponents by pointing their index finger at another player’s mouth.

Vancouver won the first two games on its home ice, turning both games in their favor in the third period before dramatic late game-winners by Raffi Torres and Burrows.

Game 3 already was essentially over before it even got that far.
