After their 5-4 preseason finale overtime loss to the Pittsburgh Penguins on Friday, the Buffalo Sabres reduced their roster to 28 players by returning four players to the AHL Rochester Americans, including 2025 first-rounder Radim Mrtka, blueliners Vsevolod Komarov and Zach Metsa, and injured center Noah Ostlund. On Sunday, the club placed forward Josh Dunne on waivers to get down to 27 players. If Dunne clears, he will be sent down to the Rochester Americans of the AHL.
