John Moore scored the tiebreaking goal at 17:03 of the third period as the Boston Bruins defeated the host Montreal Canadiens 3-2 Saturday night.

David Backes and Jake DeBrusk also scored for the injury-riddled Bruins, who extended their point streak to five games (3-0-2). Tuukka Rask made 31 saves for Boston, which has been without five regulars from its lineup.

Jonathan Drouin and Tomas Tatar scored for Montreal, and Carey Price made 32 saves. The Canadiens' winless streak reached four games (0-2-2).

Moore, a defenseman, got the winner while Drouin was serving a four-minute, double-minor penalty for a high stick against Backes. It was Moore's first goal of the season, his first in Boston.

David Krejci started the play on the side wall, feeding a pass to the front of the net where Backes was stationed. Backes tried to make a pass to the far post, but it deflected off a Montreal defenseman and right to Moore in the left faceoff circle. His blast gave Price no chance.

Trailing 2-0, Montreal rallied in the third period.

Drouin scored at 6:46 off assists from Karl Alzner and Victor Mete. Drouin gathered the puck at his own blue line and skated through three Boston players before slipping a shot between Rask's pads, the puck trickling over the goal line.

Tatar tied it with a power-play goal at 10:09 with assists from Andrew Shaw and Kenny Agostino.

The Bruins scored twice in a 1:41 span late in the first period.

Backes opened the scoring at 13:01 with an unassisted goal, stealing the puck from rookie Montreal forward Jesperi Kotkaniemi at the Canadiens' blue line and beating Price with a wrist shot from between the faceoff circles. It was Backes' first goal of the season.

DeBrusk made it 2-0 at 14:42. Bruins defenseman Torey Krug took a pass from Krejci and set up behind the Montreal net. Krug eventually skated toward the right-wing corner and fed a pass out front for DeBrusk, who had gotten a step on defenseman Brett Kulak and stuffed a short shot past Price.
