With the Blackhawks and Anaheim Ducks battling in a 2-2 deadlock during the second overtime Tuesday night, Chicago had a chance to put the away Game 2 on the power play.
Blackhawks forward Patrick Kane was stopped by Ducks goalie Frederik Andersen, but the puck bounced directly up.
That's when Chicago centre Andrew Shaw, channeling his inner Lionel Messi, jumped up and headed the puck behind Andersen.
The Blackhawks broke out in celebration and the Ducks were left confused.
However, a review of the play determined Shaw intentionally directed the puck into the net, thus negating the goal.
Undeterred, the Blackhawks rebounded as Marcus Kruger scored at 16:12 of the third overtime, giving Chicago a 3-2 win.
The best-of-seven series is now tied at one game apiece.
