Boston had 2:27 remaining on the penalty kill to open the third, during which it held Buffalo scoreless. However, Josh Norris’ empty-net tally at 19:45 brought the contest to its final 4-1 scoreline.

“We want to play with energy, and we want to play with passion. I think the best way to do that is from a place of feeling good and having fun,” Sean Kuraly said. “For whatever reason, it’s a little harder for us right now. But, we’ve got to get back to that. And we’ll find a way to.”​

The Bruins are back in action on Monday when they face the Calgary Flames for a 9 p.m. ET matchup at Scotiabank Saddledome.

“Today, since the start to probably the finish, was just not a good day that we wanted. But you know what, it’s over. I think we all have to analyze this one today, and we have to move forward because it’s not going to get easier,” head coach Marco Sturm said. “It’s definitely more on us now just to get back to our foundation, back to our game. And it starts with a good practice tomorrow, and hopefully a good game in Calgary.”
