Sabres Notes: Luukkonen, Kesselring, Mrtka

The Sabres issued multiple injury updates today, none of them particularly positive. Goaltender Ukko-Pekka Luukkonen is dealing with a new injury unrelated to the one that’s kept him out of commission thus far, head coach Lindy Ruff told WGR Sports Radio 550’s Paul Hamilton. According to Ruff, Luukkonen’s injury will keep him sidelined on a week-to-week timeline, ruling him out for the Sabres’ season-opening contest and perhaps several more after that.

Luukkonen, 26, has emerged as the Sabres’ undisputed number-one netminder over the last two years. He was brilliant in 2023-24 posting a .910 save percentage in 54 games, but took a step back in 2024-25. (.887 save percentage across 55 games) With Luukkonen sidelined moving forward, the Sabres will turn to one of Alex Lyon or Alexandar Georgiev as the team’s season-opening starting netminder. Georgiev was signed to a league-minimum deal just before the preseason, while Lyon signed a two-year $1.5MM AAV deal earlier in the offseason.

Some other notes from Western New York:

• Luukkonen was not the only Sabre Ruff said would be out week-to-week: he also noted that defenseman Michael Kesselring would be out of commission on a similar timeline. That’s a tough blow for the Sabres, who acquired Kesselring in the JJ Peterka trade and had hoped his addition would go a long way to shoring up their defense. He still could, of course, but it now appears he’ll miss at least the start of the season. In his place, the Sabres could elevate Conor Timmins from the third pair to play next to Owen Power on the team’s second pairing, or Jacob Bryson could draw into the lineup to fill that role.
• Ruff also said today that 2025 first-round pick Radim Mrtka is dealing with an illness and will be unable to play in the short-term as a result. Because of this, Rochester Americans defenseman Zach Metsa will be recalled to play in his place in the team’s final preseason game. Metsa, 26, is an NCAA National Championship-winning defenseman who scored an impressive 46 points in 69 games last year for the Americans. He’s expected to begin the season in Rochester, but if his stellar play continues he could be a name to watch for an NHL call-up down the line.
