Malmö's star player Kuokkanen had to leave the ice early in the second period after a head-on collision on Skellefteå's Oliver Okuliar, which meant a match penalty after video review.
Then the home team scored four goals in seven minutes and pulled away to 5-0, after Jonathan Pudas also scored in the first period.
In the break, Malmö's Johan Ivarsson raged.
It's so damn much whining and victim mentality. Says something about this whole community. Pathetic.
We are ready to go to war and they are on a Sunday cruise. They look down at the ice and do not defend themselves. I do not know what they are doing, said Ivarsson to TV4.
Skellefteå coach Daniel Hermansson strikes back.
It's one of the worst things I've heard. Catastrophe. It's a clear head-on collision. If that's what he's referring to, he needs to start thinking a bit.
It's them who are whining throughout this entire game, said Hermansson to the channel.
In the third period, Filip Björkman reduced with a consolation goal to 1-5, but no closer than that came Malmö, which continues to be in the bottom layer of SHL. Skellefteå is third in the table.
