The Panthers thought they had scored to cut Edmonton's lead to 2-1 off a goal from Sasha Barkov, but after a video review, the goal was ruled offside, a difficult call to make given how close the puck is to the line.
To little surprise, Panthers head coach Paul Maurice was visibly unhappy by the close call, blasting the refs decision from the bench in an apparent expletive-ridden rant.
Maurice's anger continued on post-game, with the coach continuing to vent his frustration over the goal, which Maurice felt wasn't clear enough for a challenge.
The Florida Panthers lost the game 5-1, losing a 3-0 series lead to drop even, setting up a pivotal game seven against the Oilers at home in Florida with the winner hoisting the cup.
