Morning skate revealed several adjustments as Boston prepares to face Montreal, starting with the blue line. Newly claimed defenseman Vladislav Kolyachonok will make his Bruins debut tonight, drawing in while Victor Söderström comes out.

Kolyachonok is expected to pair with Mason Lohrei, a combination that immediately stands out. Both defenders are mobile and still developing, making this a true evaluation game in a high-pressure environment.

Up front, Morgan Geekie is back where many fans like him most. He rejoins the top line alongside Elias Lindholm and David Pastrnak, restoring a trio that has shown chemistry earlier this season.

Geekie's promotion reflects recent production and trust. His ability to retrieve pucks and finish chances complements Pastrnak's creativity while allowing Lindholm to drive play through the middle.

Another notable change is the return of Viktor Arvidsson. After missing time with injury, Arvidsson is back in the lineup and slots in on the second line with Casey Mittelstadt and Pavel Zacha. His speed and forecheck instantly raise the pace of that unit.

Kolyachonok's debut is a low risk look at a player who could factor into the rotation moving forward. Rivalry games expose weaknesses quickly, but they also reveal who can handle pressure.

Geekie returning to the top line is a nod to chemistry over experimentation. Boston needs familiarity right now, especially during a stretch where confidence has wavered.

Arvidsson's return may be the most important element. His straight line speed and defensive effort have been missed, and his presence pushes others into more natural roles.

This lineup will be tested immediately. Montreal thrives on emotion and pace, and Boston's adjustments aim to meet that head on.

Tonight is not just about two points. It is about seeing whether these changes bring clarity. The Bruins will find out fast.
