A big no-call set the stage for John Tavares' heroic game-tying goal.
New York Islanders forward Matt Martin appeared to trip Florida Panthers forward Vincent Trocheck at the one-minute mark of the third period while the Islanders' net was empty.
No penalty was called on the play, and seconds later Tavares potted the game-tying goal to send the game to overtime.
Tavares would score the series winner in double overtime to eliminate the Panthers.
