The Florida Panthers and Carolina Panthers played the sixth-longest NHL game ever Thursday night into Friday morning, totaling just under 140 minutes of game play.

The game ended minutes shy of 2 a.m. on the East Coast when Matthew Tkachuk scored the game-winning goal with 12.7 seconds left in quadruple-overtime.

Given the time the game ended, the Panthers created an excuse note fans could use to get out of work or school Friday.

Florida found the back of the net in the first overtime, but it was called back due to goaltender interference.

The game lasted so long even Tkachuk didn't feel like celebrating. After scoring the game-winner, he pointed directly toward the tunnel in the arena, instructing his team to get off the ice and into the locker room to celebrate.
