The teams haven't played since April 25, when the Bruins scored four times in the third period for a 7-4 win in Game 7 of the Eastern Conference First Round of the 2018 Stanley Cup Playoffs.
In the second game, the Calgary Flames play the second of a three-game California trip when they face the Los Angeles Kings at Staples Center (10 p.m. ET; CBC, SN, SN360, FS-W, NHL.TV). It will be the third game for the Kings under new coach Willie Desjardins, who got the job after John Stevens was fired Sunday; they've split the first two. Calgary's 3-2 loss at the Anaheim Ducks on Wednesday ended its four-game winning streak.
