SAN JOSE >> Injured forwards Nico Sturm and Klim Kostin will not suit up for the San Jose Sharks anytime soon.

Sharks coach Ryan Warsofsky said Thursday that Sturm and Kostin are considered more week-to-week with their respective injuries rather than missing just a few more days.

Kostin has a lower-body injury and has not played since Jan. 10, when the Sharks faced the Utah Hockey Club in Salt Lake City. Sturm, also out with a lower-body ailment, was placed on injured reserve on Wednesday, the same day the Sharks claimed forward Walker Duehr off waivers from the Calgary Flames.

Sturm, a pending unrestricted free agent, has 11 points in 41 games this season. He centers the Sharks’ fourth line, and is the team’s leader in faceoff percentage (63.2). This season, the Sharks were 2-5-2 without him in the lineup before Thursday’s game against the Nashville Predators.

Sturm blocked a shot in a game against the Tampa Bay Lightning on Jan. 2 and missed the next three games. He returned on Jan. 11 and played five games with a goal and an assist before he sat out Tuesday’s game in Nashville, where the Sharks coughed up a four-goal lead in a devastating 7-5 loss.

“It’s frustrating because he’s probably been our most consistent forward here as of late,” Warsofsky said of Sturm. “I give him a lot of credit. He’s really improved this game in the last couple of years. He’s playing with the puck more; he’s in the offensive zone more. He’s holding on to pucks down low.

“We’re going to miss him.”

It was not immediately clear how much more time either Sturm or Kostin would have to miss. After Thursday, the Sharks have six more games before the NHL breaks for the 4 Nations Face-Off on Feb. 8, then resume their regular season schedule on Feb. 23 on the road against the Calgary Flames.

Sturm is in the final year of a three-year, $6 million contract he signed with the Sharks in 2022. Speaking with Bay Area News Group late last month, Sturm said without a new contract offer from the Sharks, he expected to be dealt to another team before the NHL trade deadline on March 7,

“Realistically, as long as nothing’s done, I might probably expect to get moved,” Sturm said. “If there’s no contract extension, that’s just the reality of life in the NHL.”

Kostin has been skating recently and was on the ice Thursday morning with fellow winger Collin Graf, who was a healthy scratch against the Predators.

Kostin, acquired last season from Detroit, is a pending restricted free agent as he is in the final year of a two-year, $4 million deal he signed with the Red Wings in 2023. He has four points in 26 games with the Sharks this season.

Duehr, listed at 6-foot-3 and 215 pounds, made his Sharks debut on Thursday night as he started the game on a line with Alexander Wennberg and Nikolai Kovalenko. Before he was placed on waivers on Tuesday, Duehr had played in just 16 of 45 games with the Flames this season and had just one assist, as he had fallen out of favor with Calgary’s coaching staff. From 2022 to 2024, Duehr played in 67 games with the Flames with a combined 18 points.

Duehr, in a contract year and a pending unrestricted free agent, wants to take advantage of his fresh start.

“It’s huge for me,” Duehr said. “I think I’ve shown at times that I belong in this league, and I’ve had good stretches. But it’s a fresh start, a new group and coaching staff that I’ve got to prove to. So I’m excited for that opportunity.”

FIRST RESPONDERS NIGHT >> Sharks winger Tyler Toffoli knows several people affected by the devastating wildfires in the greater Los Angeles area and is happy the City of San Jose and the Sharks were doing their part to support firefighters and first responders.

The Sharks hosted their second annual First Responders Group Night at SAP Center on Thursday. Along with other efforts, a portion of each ticket purchased through the group sales department supported the National Law Enforcement Officer Memorial Foundation.

“It’s definitely an emotional time,” said the 32-year-old Toffoli, who spent the first seven-plus seasons of his NHL career with the Los Angeles Kings. “I know my wife (Cat) has been on top of that, and she’s emotional about it, too. (Seeing the support), it’s an amazing thing.”

Multiple deadly fires have ripped through parts of the Southland, with the largest affecting the Pacific Palisades neighborhood and killing 11 people after being ignited on Jan. 7. The Eaton Fire, which broke out the same day near Altadena, has killed 17 people.

The Hughes Fire ignited Wednesday north of Los Angeles and has spread more than 15 square miles as of Thursday. More than 50,000 people have been under evacuation orders or warnings.

The Sharks are auctioning first responder-themed Sharks jerseys with crest and patch artwork designed by local color artist Sylas Jumper, a fire captain at the Presidio of Monterey. The auction continues through today at noon (PT). Net proceeds benefit the San Jose Fire Fighters Burn Foundation. Fans can text “SHARKSJERSEYS” to 76278 to participate in the auction or visit www.sharksjerseys.givesmart.com.

Also, proceeds from the Sharks Foundation’s 50/50 raffle on Thursday benefited the California Fire Foundation. Earlier this month, the San Jose Fire Department had sent two engines with teams to the affected areas, part of a much wider effort that saw over 15,000 people deployed.

“I’m not quite sure how many firefighters ended up going down to help,” Toffoli said. “But it’s not just everybody else who was there. Amazing job.”
