The Minnesota Wild appeared to catch a major break Wednesday against the Chicago Blackhawks.

It all started when Zach Parise scored to tie the game in the second period.

But hold the phone ... literally. The Blackhawks challenged the play, claiming Parise was offside while Charlie Coyle had the puck on his stick entering Minnesota's offensive zone.

The officials used a smartphone to communicate with the league office in Toronto during an extensive review of the play.

Here's the sequence in its entirety, at the end of which the NHL upheld the on-ice crew's ruling due to inconclusive evidence to the contrary:

"Review was not conclusive in determining whether Parise had tagged up at the instant the puck touched Charlie Coyle's stick," the league explained in a statement shared by Chicago Sun-Times' Mark Lazerus.

"According to Rule 78.7, 'If a review is not conclusive and/or there is any doubt whatsoever as to whether the call on the ice was correct, the on-ice official(s) will be instructed to confirm their original call," the NHL added.
