It will be the 17th Game 7 in Cup Final history and first since the Bruins defeated the Vancouver Canucks 4-0 on the road in 2011. That was Boston's first Game 7 with the Cup on the line.
The Bruins won 5-1 in Game 6 at St. Louis on Sunday to extend the best-of-7 series.
"There is no time to be worried or nervous about this situation," Boston defenseman Charlie McAvoy said afterward. "There are guys who never get a chance to play here, and I'll be darned] if spend a second not being grateful and just playing the best that I can. Because I'll look back on it one day, and all you can do is be thankful for these opportunities. You've just got to go out and have fun."
