Dunne (undisclosed) was placed on injured reserve Thursday, Heather Engel of NHL.com reports.

EDGE Analysis

The Sabres announced Wednesday that Dunne is expected to miss 4-6 weeks, so it isn't surprising to see him officially placed on injured reserve. The 27-year-old will presumably be sidelined until after the Olympic break, which concludes in late February.

Dunne (undisclosed) is expected to miss 4-6 weeks, Paul Hamilton of WGR Sports Radio 550 reports Wednesday.

EDGE Analysis

Dunne will likely return after the Olympic break, based on that timetable. He has a goal, four points, 34 PIM, 34 hits and 12 blocks in 28 appearances in 2025-26. Dunne hasn't been able to stay in the lineup consistently, so there's no guarantee he'll play regularly once he's available.

Dunne is being further evaluated by team doctors and could miss some time, Paul Hamilton of WGR Sports Radio 550 reports Tuesday.

EDGE Analysis

Dunne has been in and out of the lineup as a healthy scratch, but it appears that maybe he was dealing with this undisclosed injury as a contributing factor. Even when he has played, the 27-year-old center has struggled to produce offensively with just one goal and three assists in his 28 outings.

Dunne logged an assist and two hits in Tuesday's 3-2 overtime win over the Senators.

EDGE Analysis

Dunne remains a part-time option on the fourth line for the Sabres. The 27-year-old had gone five games without a point prior to Tuesday, and he was scratched five times in that span. For the season, he's contributed four points, 18 shots on net, 25 hits and 29 PIM over 23 appearances in his first season as an NHL regular despite the limited playing time.

Dunne registered an assist and four hits in Saturday's 3-2 shootout win over the Wild.

EDGE Analysis

Dunne has slipped into a part-time role over the last week, getting scratched in two of the Sabres' last five games. The 26-year-old fills a fourth-line role when he plays, though he may sit more often if Jordan Greenway can stay healthy. Dunne has earned three points, 14 shots on net, 27 PIM, 21 hits and a minus-3 rating across 17 appearances this season, surpassing his total of NHL games from his first three campaigns combined.

Dunne scored a goal on three shots in Tuesday's 4-3 overtime loss to the Blue Jackets.

EDGE Analysis

Dunne's first career goal came against the team that gave him his NHL debut in 2020-21. The 26-year-old has a goal, five shots, six hits and a plus-1 rating over four appearances this season. He's helping the Sabres cover some injury absences, but Dunne will likely have to head back to AHL Rochester once the Sabres get healthier.

Dunne was summoned from AHL Rochester on Saturday.

EDGE Analysis

Tyson Kozak (lower body) won't play Saturday against Toronto after exiting Friday's 5-3 win over the Maple Leafs. Dunne's promotion gives the team 13 healthy forwards on the roster. He might spend the rematch against Toronto in the press box, but he could plug into the lineup in a bottom-six capacity if Buffalo wants to rest a forward. Dunne has no points and three hits in two appearances with the Sabres in 2025-26.

Dunne was reassigned to AHL Rochester on Wednesday.

EDGE Analysis

Dunne's demotion could be an indication that Beck Malenstyn (personal) will rejoin the team for Wednesday's clash with the Red Wings. In his two outings this season, the 26-year-old Dunne failed to register a point while notching three hits and one shot in only 6:30 of ice time. He hasn't recorded a point in 18 career NHL outings. Given his offensive limitations, Dunne figures to spend the bulk of the campaign in the minors.

Dunne was promoted from AHL Rochester on Friday.

EDGE Analysis

Dunne's elevation to the main roster doesn't bode well for the availability of Josh Norris (upper body) ahead of Saturday's clash with the Bruins. In his two games with the Sabres last year, the 26-year-old Dunne registered five hits, five PIM and one shot but zero points. Even if Norris can't play Saturday, Dunne is far from a lock to make the lineup, especially if Zach Benson (face) is good to go.

Dunne was placed on waivers Sunday to be assigned to AHL Rochester.

EDGE Analysis

Dunne notched 10 goals and 29 points in 68 regular-season games for AHL Rochester in 2024-25. He hasn't earned an NHL point in 16 career regular-season appearances.
