Jonathan Quick content to play Rangers backup behind Igor Shesterkin

Jonathan Quick signed with the Rangers knowing he wouldn’t play often, as a 37-year-old backup goaltender to Igor Shesterkin, and the three-time Stanley Cup champion is OK with being behind Shesterkin.

“It’s good. It’s kind of as expected, right?” Quick said after the Rangers practiced on Wednesday, with Shesterkin expected to start a fourth straight game to open the season, against the Predators at Madison Square Garden on Thursday night.

“I knew the deal coming in here, who my partner is,’’ Quick said. “You come in and you work. I’m getting plenty of reps in practice. When my number is called, I’ll be ready to do everything I can to help this team win a game.”

One might think the 16-year veteran’s routine would change based on the lack of playing time, but Quick said that has not been the case.

“Not necessarily,’’ Quick said. “I’m not approaching practice any differently than I would have if I was playing like I was 10 years ago. You always come into every practice trying to improve your game. You pick something to work on, so it’s the same approach.”

Quick lost his starting job with the Kings midway through last season and was traded first to the Blue Jackets and then to the Golden Knights after they had injuries to multiple goalies.

He played regularly until Vegas’ goalies returned and Quick found himself without a role.

While he raised the Cup for the third time in his career after the Golden Knights beat the Panthers, he didn’t play during the postseason.

With Shesterkin, 27, firmly entrenched in the starting spot in net for the Rangers, Quick is content to wait his turn.

He figures to get some action on the upcoming five-game road trip that begins Saturday in Seattle and continues through western Canada.

Quick said he has talked about his schedule with the coaching staff.

“There have been discussions,’’ Quick said. “I’m confident in how they run it. Obviously, I’m one of 20 here in the locker room and you do your part day after day.”

As he said of his backup role during training camp, after he signed a one-year, $825,000 deal to come to the Rangers following a 10-year, $58 million contract with Los Angeles: “I don’t feel like it’s a different job. My job still is to stop the puck when called upon.”

Still, Quick is making an unusual transition from elite Cup-winning goalie to potentially little-used backup.

“I knew how it was gonna be run coming into it and I came in willingly,’’ Quick said. “I’m enjoying coming in every day and doing my part.”

As for his mindset, Quick said he’s just working on his game.

“No matter whether I’m playing every other night or playing every couple weeks, that doesn’t change,” he said.

In the meantime, he’s working with Shesterkin, who started a career-high 58 games last regular season.

“He’s an awesome guy off the ice and he’s so much fun to watch on the ice,’’ Quick said.

For now, Quick will get to keep watching.
