Blackhawks' Toews has goal controversially disallowed after review

A huge, controversial swing occurred in the second period of Sunday afternoon's Western Conference final game between the Chicago Blackhawks and the Los Angeles Kings. 

Early in the period, Jonathan Toews cut into the slot and scored a goal that found its way into the net off of the skate of Kings defender Slava Voynov. The play was called a goal on the ice, but was ultimately disallowed upon review.

The puck clearly deflected in off of Voynov and it was called a goal on the ice. It's unclear why exactly the goal was disallowed. While Toews did make significant contact with Kings goaltender Jonathan Quick, goaltender interference is not reviewable according to the NHL rule book. 

According to a league release, "The referee's original call on the ice was "good goal" but a discussion between the on-ice officials resulted in a "no goal" decision because Toews made incidental contact with (Quick) before the puck crossed the goal line." As such, this goal wasn't overturned upon review - it was overturned thanks to a conference between the officials. 

The Blackhawks and head coach Joel Quenneville were livid about the call, and with apparent good reason. Moments later Kings forward Tyler Toffoli scored to tie the game 1-1. Could this controversial decision swing Game 1 of the Western Conference final?
