MONTREAL -- Tyler Seguin scored 14 seconds into the third period and the Boston Bruins took their first lead of the game 1:51 later on David Krejci's goal, taking a 2-1 win over the Montreal Canadiens on Wednesday night at the Bell Centre.
Tuukka Rask stopped 21 shots for Boston (7-1-1). The Bruins have yet to lose on the road through regulation (3-0-1).
P.K. Subban scored his first goal on a power-play midway through the first and Carey Price made 21 saves for Montreal (6-3).
The Canadiens, who swept a pair of weekend matinee games against Buffalo and Ottawa at the Bell Centre, are 5-2 at home.
Krejci assisted on Seguin's goal, which tied it at 1. Seguin got his second point with an assist on Krejci's goal at 2:05. The Czech center drove to the net to direct Milan Lucic's pass into the net for his third goal in five games.
