The moves leave the Sabres with 29 players on their camp roster, though that number includes goalie prospect Topias Leinonen, who has missed all of camp thus far with a lower-body injury.

NHL teams must finalize their 23-man rosters for the start of the regular season by 5 p.m. on Monday.

Buffalo’s remaining camp roster is as follows:

Forwards (16): Zach Benson, Sam Carrick, Justin Danforth, Josh Doan, Konsta Helenius, Tyson Kozak, Peyton Krebs, Jiri Kulich, Beck Malenstyn, Ryan McLeod, Josh Norris, Noah Ostlund, Jack Quinn, Conor Sheary, Tage Thompson, Jason Zucker

Defensemen (9): Louis Crevier, Rasmus Dahlin, Matt Grzelcyk, Zach Metsa, Owen Power, Jack Rathbone, Mattias Samuelsson, Conor Timmins, Olen Zellweger

Goaltenders (4): Colten Ellis, Topias Leinonen, Ukko-Pekka Luukkonen, Alex Lyon

Sept. 25 – Injury updates from Friday’s practice

Following Friday’s practice at KeyBank Center, coach Lindy Ruff provided the following injury updates:

  • Goalie Alex Lyon is still being evaluated for the upper-body injury sustained in Thursday’s game. The team should have more details Saturday.
  • Forward Jiri Kulich, who exited the Detroit game as a precaution, missed practice for maintenance. He’ll likely skate Saturday but not play in the preseason finale.
  • Defenseman Mattias Samuelsson (lower body) told Ruff, “This isn’t gonna be that long.” It’s a question of pain tolerance, and Ruff thinks Samuelsson could return on the early end of his week-to-week timeline.
  • Defenseman Olen Zellweger (concussion protocol) has progressed to skating. “In all likelihood, I would anticipate him being ready for next week,” Ruff said.
  • Forward Noah Ostlund missed practice for maintenance after playing 23:56 on Thursday.

Sept. 25 – Sabres sign Grzelcyk to 1-year deal

The Buffalo Sabres have signed defenseman Matt Grzelcyk to a one-year contract worth $850,000.

Grzelcyk, 32, is a veteran of 596 games spanning 10 NHL seasons. He spent 2025-26 with Chicago, tallying 12 assists in 69 games.

The addition gives the Sabres another left-shot defenseman in the wake of injuries to Mattias Samuelsson (lower body, week to week) and Olen Zellweger (concussion protocol).
