Jaromir Jagr scored his second goal as a member of the Bruins and Boston ended a four-game winless streak with a 3-0 victory over Florida on Sunday.
The Bruins were playing the second of back-to-back afternoon games after hosting the Penguins in a 3-2 loss Saturday. The game was originally scheduled for Friday night, but postponed because of the lockdown and manhunt for one of the suspected Boston Marathon bombers.
Tuukka Rask stopped 28 shots for his fourth shutout of the season and the Bruins pulled into a tie with idle Montreal for first place in Northeast Division with 59 points.
The Bruins have four games to play, one more than the Canadiens as the longtime rivals try to lock up the division in the final week of the regular season.
