One of the homemade signs by the glass Monday before the Carolina Hurricanes game at the Lenovo Center said simply, “Welcome back, Jarvy.”

And what a way to come back.

Sidelined seven games with an injury, antsy to get back in the fight, Seth Jarvis returned to make an immediate impact as the Hurricanes took a 6-4 win over the Dallas Stars on the strength of a five-goal detonation in the third period that had the arena rumbling.

Jarvis scored shorthanded in the first period.

He set up Sebastian Aho for a goal early in the third to ignite things.

He assisted on a Martin Necas power-play score that would be the winning goal with 2:07 left in regulation, as a Necas pass glanced off the skate of defenseman Ilya Lyubushkin in front and past goalie Jake Oettinger.

“You’re not really sure how the kid is going to respond,” Canes coach Rod Brind’Amour said of Jarvis. “He doesn’t even practice, except on his own. You don’t know what he’s going to bring.

“He was, I thought, the best player on the ice. He’s a special player. We’ve known that. To do it after sitting out a couple of weeks says a lot about him.”

Jarvis anything but rusty

Jarvis had not played since the Nov. 9 game at Colorado, missing time with an upper-body injury, and not did join the Canes on their recent three-game road trip. He was activated off injured reserve on Sunday and at the morning skate Monday..

Jarvis, never lacking energy. was not rusty or sluggish come game time. On a Stars power play in the first period, he knocked down the puck near the Carolina blue line and got it up the boards to Aho, speeding down the middle of the ice to beat Oettinger with a backhander.

Jarvis’ description:

“A good play at the line just to keep it out. I know ‘Fishy’ is going to jump, so it was kind of just keep up with him. He made a great pass over to me and it was just kind of knowing the goalie is going to slide … and just kind of put it on net.”

Jarvis smiled, adding, “Sometimes, I surprise myself. I’ve got a little bit of skill deep down.”

That would be the Canes’ only goal in the first 40 minutes as the Stars (13-7-0), who had won five of their last six, took a 3-1 lead into the third and appeared to be grinding their way to victory.

But Aho and Jarvis teamed up again, Jarvis making a pass off the wall to Aho breaking in off the rush to make it a 3-2 game.

That, Brind’Amour said, was the turning point in the Canes’ eighth straight win at home.

“That shift … now we’re back in it and the building kind of got going,” he said. “You could feel the bench getting kind of juiced up and I thought we had a good period, obviously.”

Burns goal ties it up

Defenseman Brent Burns tied the score 3-3 with his first of the season, rifling a shot through traffic with winger William Carrier screening Oettinger.

“It was nice to see ‘Burnzie’ get that one,” Brind’Amour said. “He’s been kind of snakebit this year.”

The Canes had been without a power play in the game — much to the disdain of Canes fans — until the Stars’ Mason Marchment was called for high-sticking about eight minutes into the third period.

Derfenseman Shayne Gostisbhere quickly followed with a goal from the top of the slot for a 4-3 lead, only to have Stars defenseman Miro Hesikanen quiet the building with an outside shot that Martin couldn’t track with 5:16 left in regulation.

But Marchment, who had a goal and assist, high-sticked Necas. The winger then scored the go-ahead goal — his 12th of the season — and Andrei Svechnikov’s late empty-netter finished it off for the Canes (15-5-1)

“That third was exactly what we needed,” Jarvis said. “That’s a lot of credit to the older guys, keeping us composed.”

Aho finished with a goal and three assists in being named the game’s first star and Jarvis had a goal and two assists.

Not to be overlooked was Spencer Martin’s play in net. He allowed four goals on 19 shots but mixed in some high-quality saves, including a critical stop on a Roope Hintz shot in the third.

With goalie Pyotr Kochetkov out indefinitely with a concussion and Frederik Andersen having knee surgery, Martin for now is the Hurricanes’ No. 1 guy in net.

‘Spence played great. The goalie situation is all right,” Jarvis said. “Obviously you don’t want to see guys get hurt but we have all the confidence in the world in Spence.”
