There was an unfortunate development when it comes to injuries, however, as the team announced that Tomas Nosek will miss at least the next four weeks with a non-displaced fracture in his left foot. The centerman also blocked a shot during Boston's 3-1 win at MSG on Thursday night.
Nosek had already been battling through an undisclosed injury that forced him to miss the two games leading into the Winter Classic, as well as the front end of the B's back-to-back in New York this week. The ailment - which, per Montgomery, is believed to be almost fully healed - had also hampered his ability to take faceoffs up on his return, leading to Boston recalling center Joona Koppanen from Providence.
Koppanen, who made his NHL debut on Jan. 12 against Seattle and suited up again on Wednesday night against the Islanders, centered Nick Foligno and A.J. Greer during Saturday's practice.
"I thought his first game was better than his second," said Montgomery. "I thought with his second there's areas where - or things that happened in the game where he's going to learn and get better from.
"I mean, it's the NHL. You're going to sometimes be in situations where you're going to say, 'Next time, I'm going to be more aggressive or next time I'm going to do this. But he didn't hurt us at all. He helped us win that game. And then I think today in practice is the best I've seen him look."
Montgomery added that while the club will miss Nosek during this stretch, it's a positive for Koppanen to get some consistent and extended reps at the NHL level. The 24-year-old has spent parts of the last six seasons in Providence after being selected by the Bruins in the fifth round of the 2016 NHL Draft.
"It's good for him. It's good for us to know, do we have a guy who could do this daily, add to our playoff depth?" said Montgomery. "Obviously, we're looking at that for this year. Then, we're looking down the road for next year."
Boston's bench boss said that the team will need to call up another forward from Providence before the team leaves for its week-long road trip on Monday afternoon.
"I think we're going to call up someone after our game [Sunday] or Monday morning, but I don't know which one," said Montgomery. "We're going to have to, we can't just go with 12 forwards."
