A successful penalty shot by Sharks center Logan Couture in the third period Monday didn't just seal a 3-0 loss for the Wild at Xcel Energy Center.
It also provided a rules lesson.

After Couture was hooked by defenseman Anthony Bitetto during a breakaway, Couture was awarded a penalty shot – which he buried five-hole on goalie Devan Dubnyk.
The Wild then tried to issue a coach's challenge to determine if Couture was off-side on his breakaway attempt.
Initially, it looked like the sequence would get reviewed because the referee contacted the league's situation room to relay the Wild's request.
But the NHL confirmed that the Wild couldn't use a challenge since a challenge can only review a play that results in a goal. And since the breakaway didn't end up in the net, the Wild couldn't get a further look at the sequence.
"It's one of those things where you're just trying to disrupt him a little bit," Bitetto said of his hook on Couture. "I guess it's a penalty. I'm not a ref. That's a tough call. He made the call, and that's part of the game. It's kind of a weird play, to be honest."
Bitetto finished the game a minus-1 in his return to the lineup after sitting out the previous two. He was a minus-2 in his most recent game, the 5-4 shootout loss to the Predators last Tuesday in Nashville.
