Mikhail Grabovski could get a call from the NHL’s department of player safety after his boarding major and game misconduct late in the first period Sunday.

Grabovski is an unlikely Islander to face a possible suspension, but his dangerous hit that knocked Canucks captain Henrik Sedin from the Islanders’ 2-1 shootout loss was hard to justify.

“I didn’t see at all,” Sedin said. “I knew someone was there but I thought I had somehow turned away from it, so I did not expect him to hit me at that point.”

Sedin left the game and said he might be out for a while, but “we are not talking weeks, I’m hoping,” he said. That also could factor into a suspension for Grabovski.

“The league always does a good job with whatever they decide,” Islanders coach Jack Capuano said.

The Islanders were not thrilled that Derek Dorsett escaped with only a minor penalty after throwing a shoulder into John Tavares’ head early in the second period.

“It’s a guy who has a history of doing some questionable things,” Kyle Okposo said of Dorsett.

Head-scratchers in 2nd

The Islanders had a couple of brain-cramp moments in the middle period.

Grabovski’s major overlapped a few other penalties and situations. The Isles had a four-on-three power play to start the second, then played four-on-four for 1:38, then had to kill the final 1:22 of the major. But Capuano and his staff elected not to put a player in the penalty box to serve Grabovski’s major and got burned when play did not stop for 29 seconds after the end of the penalty, forcing the Islanders to play shorthanded for that stretch. And they took another penalty at the next whistle.

Canucks defenseman Ben Hutton got some help on his goal as Calvin de Haan did not have a stick as the play worked through the Islanders’ zone. De Haan broke his stick nearly a minute earlier, borrowed Nikolay Kulemin’s to help get the play out of the zone, then inexplicably handed the stick back as Kulemin went to change — and de Haan did not.
