SAN JOSE — Sharks coach Pete DeBoer said defenseman Paul Martin has suffered a setback in his recovery from an ankle injury and there is no indication yet as to when he’ll be able to return.

DeBoer said Martin’s latest malady is not a recurrence of the ankle injury that has kept him out of the lineup for the last six weeks, adding that he doesn’t foresee Martin needing another surgery. Martin has surgery this summer to repair ligaments in his ankle before he re-injured the ankle in the second week of the regular season.

Game Changers: Four years after Kaepernick kneeled, a look at Bay Area sports leaders who stood before him Martin had been skating regularly for roughly two weeks earlier this month but was not on the ice for Sunday’s optional practice or for Monday’s morning skate prior to the Sharks’ game against the Anaheim Ducks.

Martin, who has been on injured reserve since Oct. 12, will not travel with the Sharks for their road games against Arizona on Wednesday and Vegas on Friday.

“A little setback,” DeBoer said of Martin. “We’re going through the process of seeing exactly what it is, making sure we know what it is and we’ll have kind of a update.”

Joakim Ryan has played in Martin’s place alongside Brent Burns since Oct. 12 and has played in 17 straight games. Ryan has two assists and has averaged 17:44 of ice time per game.

DeBoer doesn’t feel Martin’s absence, though, has had any effect on Burns, who remains without a goal 19 games into the regular season. Like last season when Burns had 29 goals and 76 points, DeBoer feels Burns is still creating quality chances and getting plenty of shots on goal. Get Sharks news in your inbox.

“(Assistant coach) Rob Zettler did an exercise and looked back at every goal (Burns) scored last year,” DeBoer said. “When we’re looking at those tangible things, there’s not a lot of difference. It’s a really fine line.

“When they go in, they go in bunches and when they don’t, he’s gone through streaks like this before. But if he was not getting those looks, was not getting shot generation, if he’s not getting those chances, then we would be worried.

“I think Joakim Ryan’s done a really good job and the evidence we look at says it’s one of those things that he needs one and hopefully the floodgates open.”

▪ Forward Melker Karlsson, who missed Monday’s game with an upper body injury, skated Tuesday in a non-contact jersey. Karlsson made the trip to Arizona but it is not known if he’ll play either Wednesday or Friday when the Sharks play the Vegas Golden Knights.

▪DeBoer kept Meier on the top line with Pavelski and Joe Thornton for Tuesday’s practice. Meier was moved from the fourth line to the first line late in the second period of Monday’s game as he took Kevin Labanc’s spot. Labanc was on the third line with Chris Tierney and O’Regan.
