The new rule governing lost offside challenges cost the Chicago Blackhawks in a loss to the Minnesota Wild on Thursday night, and coach Joel Quenneville was not happy about it.

"It's gotten to a different level," Quenneville told reporters postgame, via the Chicago Sun-Times' Mark Lazerus.

"I don't know the rules anymore or something's changed, because my understanding, (having) played a lot of hockey, (was) that … I don't know. I think everybody has an interpretation (of) what's a good goal and what's a bad goal, but I can't believe it," he added before throwing up his hands and walking out of the room.

Here's the video evidence of the end of Quenneville's presser:

So what was Quenneville so upset about?

Chris Stewart scored to give the Wild a 2-1 lead midway through the third period, and the Blackhawks bench boss challenged the play hoping Minnesota forward Jason Zucker would be deemed offside carrying the puck in before setting up Stewart for the go-ahead marker.

But the goal call was upheld, and because of the NHL's new policy of assessing a penalty against the team that loses an offside challenge, the Wild went on a power play as a result. Zucker scored on the man advantage to make it 3-1 for Minnesota. Stewart followed that with another goal, and the Wild cruised to a 5-2 victory.

The NHL offered an official explanation postgame, citing Rule 83.1, which states, in part:

"If a player legally carries or passes the puck back into his own defending zone while a player of the opposing team is in such defending zone, the off-side shall be ignored and play permitted to continue."

This is the first season the league is penalizing teams for failed offside challenges.
