All four games in the series have been won by the road team. The Bruins are home Saturday night after tying the series at 2-2 with a 5-4 overtime win on Thursday night.
Boston coach Claude Julien said Friday the way his team plays is more important than where it plays.
The Bruins rallied from deficits of 1-0, 3-1 and 4-3, and several players said they did it by sticking with their game plan rather than changing when they were behind. They didn't practice on Friday after an early-morning flight from Montreal.
Boston won the game on former Canadien Michael Ryder's second goal of the night.
