It’s the most controversial play of the series, and Toronto Maple Leafs fans are up in arms.

Down 2-1 in the second period, Morgan Rielly appeared to tie the game up. The Leafs defenceman took the puck to the net, and then it disappeared under the pad of Florida Panthers goaltender Sergei Bobrovsky.

After a lengthy video replay, it was determined that the puck didn’t cross the goal line before the referee’s whistle had blown.

You be the judge:

Leafs fans were furious too.

Spectators at Scotiabank Arena chanted “bullsh*t,” and littered the ice with debris.

Loud chants of "Bullshit! Bullshit!" at Scotiabank Arena. Reminds me of the chaotic atmosphere at Rogers Centre the night of the Bautista bat flip.
