SAN JOSE — Sharks coach Pete DeBoer heard from the NHL on Tuesday — just as he predicted the night before — but didn’t want to elaborate on what the league’s representative might have said.

“I did hear from somebody with the league, but I’m not going to share with you those conversations,” DeBoer said. “But I did (hear).”

There appeared to be a handful of officiating missteps in the Sharks’ 6-5 overtime loss to the Boston Bruins on Monday. DeBoer after the game noted the lack of an extra penalty on Zdeno Chara for his dust-up with Joe Pavelski, Chris Wagner’s disputed tying goal with 1:49 left in the third period and the Bruins’ net not being put back on its moorings in overtime and the whistle being blown prior to an Evander Kane breakaway.

“I’m sure we’ll get an explanation and some type of apology,” DeBoer said Monday night. “It doesn’t help us in the standings, but that’s usually how it works.”

On his goal, Wagner had a shot from in close that was blocked by Sharks goalie Martin Jones. The puck flew straight up into the air before Wagner knocked the puck into the net with a stick that appeared to be above his shoulders.

“I kind of just swiped at it. It bounced up and I think I got it at shoulder level,” Wagner said after the game. “I put it in before, so I knew (the Sharks) couldn’t challenge it. It was a good goal on the ice and they didn’t call a high stick right away. (The Sharks) were probably upset about that.”

There was some question as to whether Wagner made contact with the puck before it crossed the Sharks’ goal line. But according to NHL rule 80.1, “when a puck is struck with a high stick and subsequently comes into the possession and control of a player from the offending team (including the player who made contact with the puck), either directly or deflected off any player or official, there shall be a whistle.”

The Bruins won the game on Charlie McAvoy’s goal at the 3:59 mark of overtime.

▪ The Sharks’ penalty kill was 2-for-4 against the Bruins, as San Jose has now been shorthanded 32 times — fourth most in the league — in eight games so far this month.

The Sharks have given up five power play goals in that span. But it’s not just the amount of penalties that bothers them, it’s the type of penalties that they’re taking.

“Just lazy penalties,” said Sharks center Logan Couture, who lamented his second period hooking penalty on Chara. “When you’re penalized (five) times in Winnipeg, (seven) times in Calgary, it’s tough on guys that play the PK, that play a lot of minutes that are counted on to be good offensively as well.

“When you’re playing four or five minutes on the kill, it’s not easy to jump out there and have energy for a regular shift.”

Monday night, three of the Sharks penalties were for high sticking and another was for hooking. Against Vancouver on Saturday when they killed all four of their penalties, two calls were for tripping and one was for hooking. Against Washington on Feb. 14, two penalties were for tripping, one was for high-sticking and another was for holding.

“It’s just uncharacteristic,” DeBoer said. “A lot of high sticks, trying to lift other guys’ sticks and catching guys in the chin. Stick penalties. I didn’t think last night it was lazy penalties. They were more a little bit unfortunate. Guys trying to get underneath people and missing and catching them in the head.

“I thought (against Vancouver), I thought we took a couple lazy penalties where we got on the wrong side of people and just were reaching and tripping. As the playoffs get closer, that’s a big part of playoff hockey, having that discipline and not putting teams on the power play. It stung us last night.”

▪ Erik Karlsson was given a maintenance day Tuesday by DeBoer and didn’t skate. Karlsson, who recently missed nine games with a groin injury, played 28 minutes and 33 seconds against the Bruins.

▪ Joonas Donskoi was back on a line with Tomas Hertl and Evander Kane for Tuesday’s practice, and Lukas Radil was back with Barclay Goodrow and Melker Karlsson. DeBoer switched Donskoi and Radil for the second half of Monday’s game, saying afterward, “I thought Donny could’ve been better. That was a heavy game out there. I thought Radil was giving us a little bit more of that.”

▪ The Sharks recalled center Dylan Gambrell from the Barracuda on Tuesday afternoon. Gambrell had two assists for the Barracuda on Monday in its 5-2 win over San Diego.
