There was just 4:45 left in regulation, and the Penguins were clinging to a one-goal lead that would have sent them to Raleigh for the second round of the Stanley Cup playoffs.
Mika Zibanejad's late goal ultimately forced overtime, setting the stage for Artemi Panarin's eventual series-clinching overtime goal. The 4-3 loss in the extra frame ended the Penguins' season.
There's naturally some controversy on the sequence that led to Zibanejad's tying goal.
Just before the goal was scored, Marcus Pettersson was engaged in a battle with Alexis Lafreniere behind the net.
