BUFFALO, N.Y. — Newly hired Buffalo Sabres general manager Jarmo Kekalainen has wasted little time reshaping the team’s front office by hiring former Montreal Canadiens GM Marc Bergevin and Josh Flynn to his staff.

The hirings, announced Sunday, come in Kekalainen’s first week on the job and a day after he fired assistant general manager Jason Karmanos. Kekalainen took over on Monday to replace Kevyn Adams, who was fired with the Sabres already in jeopardy of extending their NHL-record playoff drought to a 15th consecutive season.

“[They] bring a wealth of unique experience and perspective,” said Kekalainen, the former Columbus Blue Jackets general manager who spent the previous six-plus months as a senior adviser in Buffalo. “Adding both to an already strong group adds versatility and helps us continue to build a well-rounded hockey operations staff.”

Bergevin fills the associate general manager position and will serve as Kekalainen’s top adviser. He joins the Sabres after spending parts of the past five seasons as a senior adviser with the Los Angeles Kings.

The 60-year-old Bergevin most notably oversaw the Canadiens from 2012 to 2021, over which Montreal made six playoff appearances, including a five-game series loss to the Tampa Bay Lightning in the 2021 Stanley Cup Final. He previously worked in player personnel and scouting roles with the Chicago Blackhawks.

“Marc has firsthand experience as an NHL general manager and a track record as a strong talent evaluator,” Kekalainen said. “His insight will be invaluable as we continue to identify and develop talent throughout the organization.”

Flynn was named assistant general manager. He previously worked under Kekalainen with the Blue Jackets specializing in salary cap management, statistical research and strategic planning. Flynn’s role will be similar in Buffalo.

“I know that his attention to detail and nuanced understanding of league processes will help to enhance how we support our broader organization,” Kekalainen said.

Flynn’s responsibilities are similar to that of Buffalo’s current assistant GM Mark Jakubowski. With Karmanos’ departure, Jakubowski’s duties will likely shift more to overseeing the Sabres’ American Hockey League affiliate in Rochester, New York.

Kekalainen has also retained Sabres assistant general manager Jerry Forton, who serves as the team’s chief amateur scout.

NASHVILLE, Tenn. — New York Rangers captain J.T. Miller will miss at least one game after getting injured Saturday and is not traveling with the team to Nashville.

Coach Mike Sullivan said Miller was still being evaluated back home for an upper-body injury and would not play Sunday night against the Predators.

Miller left the Rangers’ game against Philadelphia with about eight minutes left after taking a big hit from Flyers defenseman Nick Seeler and landing awkwardly. The 32-year-old forward appeared to be favoring his right arm or shoulder while in pain on the bench and skating off to go down the tunnel for medical attention.

“You don’t want to lose any teammates,” center Mika Zibanejad said. “When you see your captain go down and you don’t see him come back, that obviously becomes [a situation] for us to step up and everyone has to do a little more when a guy like that leaves. Just hoping everything is OK.”

Miller was named captain before training camp. He has 10 goals and 12 assists in 35 games this season and is believed to be in consideration for the U.S. Olympic team, though it’s unclear whether this injury could cloud that possibility.

New Jersey Devils star Jack Hughes, out since Nov. 12 with a “freak” hand injury, will return to the lineup against the Buffalo Sabres on Sunday.

Hughes, 24, injured his hand at a team dinner in Chicago on Nov. 13, underwent surgery on his finger and was given a recovery window of eight weeks. He has been skating throughout his rehab and was recently spotting using a stick again on the ice.

He returned to Devils practice Sunday at an optional skate.

“Yeah, I’m going to play tonight. Might as well ease my way in,” Hughes joked after practice.

Both Hughes and the Devils were off to flying starts before his injury. New Jersey was 12-4-1, with the second-best points percentage (.735) in the NHL behind the Colorado Avalanche (.794) and first place in the Metropolitan Division. Hughes had 20 points in his first 17 games, including 10 goals.

The Devils struggled without their top-line center, going 8-10-0 (.444) and scoring 3.35 goals per game with Hughes to 2.28 goals per game without him. But they have remained in the playoff race in a competitive Eastern Conference, holding the final wild-card spot entering Sunday.

Hughes is one of three key players returning to the Devils’ lineup Sunday against surging Buffalo, which has won five straight games. Forward Timo Meier last played Dec. 9, having taken leave from the team for a family matter. He has 11 goals and 12 assists in 30 games. Forward Arseny Gritsyuk has missed the past four games due to injury. The rookie has 16 points in 31 games.

“To come back from the road trip and to have those guys in the building and then on the ice, it gives the [team] a boost,” coach Sheldon Keefe said Sunday. “There’s an emotional impact.”

Keefe said the challenge for his team is not to become suddenly passive because help has arrived.

“We’ve got to keep playing the way we’ve been playing and have those players enhance that,” he said. “Sometimes when you bring important people back to your group, there can be a tendency for the rest of the group to take a back seat. And that cannot happen.”

Sunday was Hughes’ first appearance since the injury and the first time he has faced questions about his brother, star defenseman Quinn Hughes, being traded to the Minnesota Wild last week.

Sources told ESPN that the Vancouver Canucks went to the Devils first in discussing trade destinations for Quinn Hughes, as his brothers Jack and Luke both play in New Jersey. Ultimately, the Canucks opted to trade Hughes to the Wild for center Marco Rossi, forward Liam Ohgren, defenseman Zeev Buium and a 2026 first-round pick.

“It happened fast,” Jack Hughes said, adding that there was a “little bit” of disappointment that the three brothers weren’t united together. “I think he’s happy in Minnesota now. They have a great team there, and they’re playing well. … We’re happy for him.”
