Buffalo Sabres goaltender Ukko-Pekka Luukkonen (undisclosed) will miss Monday's matchup against Seattle. He's battling some nagging injury issues. However, Luukkonen's absence might be limited to just one game, as he said on Sunday that he could play on Tuesday against Vancouver. Luukkonen has had a mediocre campaign as Buffalo's No. 1, going 14-14-4. He has registered a 3.02 goals-against average with a .896 save percentage and two shutouts. Devon Levi, who is 2-6-0 for the season, is expected to work in the Sabres crease on Monday.

San Jose Sharks defenseman Timothy Liljegren (illness) will return to the lineup for Monday's matchup against Boston. He was unavailable on Saturday against the Islanders due to an illness. Liljegren operates in a top-four role and logs regular power-play time in San Jose but hasn't been very impactful. Through 34 outings, the former Maple Leaf has tallied eight points (four goals, four assists) with 47 blocks and 40 hits. He has grown his tally by only three points since December. Henry Thrun played instead of Liljegren at the weekend and will remain in the lineup, with Marc-Edouard Vlasic (illness) ruled out.

San Jose Sharks forward Mikael Granlund (lower body) will be in the lineup on Monday versus Boston. It was unclear if Granlund would be available for the contest after he sat out Sunday's practice with a lower-body injury. His availability is massive for the Sharks, as Granlund has been their leading man in 2024-25. He tops the team in scoring and assists, having notched 37 points and 25 helpers in 46 games. Granlund is expected to skate with Fabian Zetterlund and Boston College product Will Smith. Recent times have been tricky for Granlund, as he has finished pointless in seven of his past 10 outings.

San Jose Sharks winger Tyler Toffoli (lower body) has been ruled out for Monday's contest against Boston. He remains day-to-day with a lower-body injury, missing a second straight game. Toffoli has posted 30 points (17 goals, 13 assists) in 47 games during his first campaign as a Shark, notching a third of the points with the man advantage. Carl Grundstrom took Toffoli's spot in the lineup on Saturday against the Islanders, with Ty Dellandrea getting a look in the top six. Alex Wennberg is projected to replace Dellandrea in that role on Monday.
