The San Jose Sharks were their own worst enemy on Sunday against the Ottawa Senators.

A host of giveaways, including one on a goal by Drake Batherson with less than seven minutes left in the third period, proved to be the Sharks’ undoing in a sloppy 7-4 loss to the Senators at the Canadian Tire Centre.

With the game tied 4-4, Sharks defenseman Dmitry Orlov retrieved the puck below the goal line and sent it behind the net, trying to find John Klingberg.

Instead, the pass went straight to Claude Giroux, who sent the puck back to Artem Zub. The defenseman’s shot from just inside the blue line went off Batherson and past Sharks goalie Laurent Brossoit for a 5-4 Senators lead.

Dylan Cozens and Brady Tkachuk added goals in the late going as the Sharks missed a chance to widen their lead in the Western Conference for the second wild card spot.

Mario Ferraro, Tyler Toffoli, Collin Graf, and Michael Misa all scored for the Sharks, with Misa’s goal, his seventh of the season, tying the game 4-4 with 16:32 left in the third period.

The Sharks announced before the game that they would be without center Alex Wennberg, who was unavailable with an upper-body injury.

It was not immediately clear how much more time Wennberg, who usually matches up against the opposing team’s top line and plays in all situations, would have to miss. Wennberg is third on the Sharks with 43 points in 64 games, and is second among the team’s forwards in average ice time (20:37).

His absence was felt, as the Sharks are now 2-2-0 on their five-game road trip that ends Tuesday against the Edmonton Oilers. The Sharks were coming off wins over the Boston Bruins on Thursday and the Montreal Canadiens on Saturday.

The Sharks on Sunday trailed 4-3 going into the third period, as the Senators scored goals after three San Jose giveaways.

Senators forwards Warren Foegele and Fabian Zetterlund scored goals after Mario Ferraro and Shakir Mukhamadullin gave the puck away along the boards. Zetterlund’s goal came on a blast from just inside the blue line, as he tied the game at the 13:40 mark.

Senators defenseman Tyler Kleven broke the tie 65 seconds later, taking a pass from Zetterlund after a Graf giveaway in the Sharks zone, and beating Brossoit to the short side for his third goal of the season.

Brossoit, recalled by the Sharks from the San Jose Barracuda of the AHL on Friday, a day after Yaroslav Askarov was lost to a lower-body injury, was making his first NHL regular-season start in almost two years. Brossoit is 11-2-1 in 14 games with the Barracuda.

On Jan. 8, the Sharks acquired Brossoit, defenseman Nolan Allan, and a 2028 seventh-round selection from the Blackhawks for the contract of defenseman Ryan Ellis, AHL defenseman Jake Furlong, and a 2028 fourth-round selection.

With his team in a playoff race, Sharks general manager Mike Grier wanted a third goalie with NHL experience in case Askarov or Alex Nedeljkovic were injured. Askarov is considered day-to-day with a lower-body injury.

Brossoit’s last regular-season NHL start came on April 18, 2024, when he made 18 saves to help lead the Winnipeg Jets to a 4-2 win over the Vancouver Canucks. His last NHL appearance came on April 28, 2024, when he entered in relief of Jets starter Connor Hellebuyck in Game 4 of a first-round playoff series against the Colorado Avalanche.

In Aug. 2024, after he signed with the Chicago Blackhawks, Brossoit had what he thought was going to be routine surgery to repair the meniscus in his right knee, with the expectation that he would be back to full health roughly six weeks later. But the knee never improved enough for him to play in a game, and it got to the point — after meeting with several specialists — that Brossoit thought he might not play again.

Last summer, Brossoit and doctors, after examining his right hip, found the root cause of the knee pain — a cam lesion on the head of his femur that was causing issues with cartilage inside the joint. Brossoit suspected this could be the issue after he had previously had problems with his left hip, which had caused back pain.

After surgery, Brossoit worked his way back and played his first game — since that start for the Jets – in December for the Blackhawks’ AHL affiliate.

Brossoit, who turns 33 next week and won a Stanley Cup with the Vegas Golden Knights in 2022-23, has now played in 141 NHL games. He came into Sunday with a record of 64-46-13 record and a .911 save percentage in stints with the Edmonton Oilers, Jets, and the Golden Knights.

It was not immediately known when Askarov would be healthy enough to play again. The Sharks finish their road trip Tuesday in Edmonton, then return home to face the Buffalo Sabres on Thursday and the Philadelphia Flyers on Saturday.

CHERNYSHOV UPDATE

Sharks forward Igor Chernyshov will not play Sunday after he sustained a concussion the previous night against the Montreal Canadiens. It was unclear when Chernyshov would be healthy enough to play. Pavol Regenda took Chernyshov’s spot in the lineup and played alongside Philipp Kurashev and

Regenda has been a healthy scratch for the last six games. He has eight goals and 19 points in 18 games with the Sharks this season.

Chernyshov had just taken a pass in the neutral zone early in the first period when he was checked by Canadiens defenseman Mike Matheson, who briefly put his right arm around the Sharks winger to try to slow him down. Chernyshov then spun around and landed awkwardly on the ice before he slid face down for several feet.

During the game, Chernyshov was taken to a local hospital for evaluation, then rejoined the Sharks at the arena and traveled with the team to Ottawa late Saturday night.
