Norris has not played since March 12th and remains sidelined with a mid-boy injury and no certainty as to when he may return to the lineup. Norris was productive early in his tenure with Buffalo, recording two points (1G / 1A) and averaging 18:36 time-on-ice but has been limited to only three games.

Reimer has started four of the last five games for the Sabres, all wins (4-0-0), and will likely return to the crease on Tuesday against the Ottawa Senators. The 37-year-old Reimer has seen limited action this season but recently came off an 11-appearance stretch (3-5-1) where he posted a solid 2.60 GAA and .911 SV% from mid-December to mid-March. Still, the Sabres enter Tuesday's contest as +161 road underdogs against a Senators team without Brady Tkachuk (upper body).

Rathbone was recalled on the weekend for precautionary reasons but did not draw into Buffalo's lineup. The 25-year-old defenseman will return to the Rochester Americans (AHL), where he has 20 points (5G / 15A) in 56 games this season.

Leinonen was a second-round pick, 41st overall, of the Buffalo Sabres in the 2022 NHL Entry Draft. The 21-year-old goalie has spent the 2024-25 season with Mora IK (Swe-1), posting a 2.31 GAA and .910 SV% in 25 games (13-10-0).

Dunne is an undrafted 26-year-old forward that played two games with the Sabres this season but has spent most of the 2024-25 campaign in the AHL. He has 26 points (9G / 17A) in 58 games with the Rochester Americans (AHL).

Dunne will slot in for Jason Zucker, who is out due to a personal matter. Dunne has appeared in just one other game for the Sabres this season and is yet to register a point through 15 career NHL games.

Lafferty did not play in Buffalo's previous game and will be held out again on Thursday against the Pittsburgh Penguins. The 30-year-old forward is averaging 9:43 time-on-ice and has five points (2G / 3A) in 50 games this season.

The Sabres are riding a two-game winning streak courtesy of two solid efforts from James Reimer, and he will return to the crease on Thursday against the Pittsburgh Penguins. The 37-year-old Reimer has saved 63 of 65 shots (.926 SV%) in his last two games (2-0-0). He has a 2.93 GAA and .900 SV% in 16 appearances this season (4-8-2). The Sabres enter Thursday's contest as -135 home favorites against a Penguins squad coming off a disastrous 6-1 loss to the Tampa Bay Lightning.
