However, to round out the second frame, Philadelphia crawled back within one once again. During an abbreviated five-on-three, Noah Cates jammed home a second effort, making it a 3-2 contest at the end of 40.
As it turned out, the quick pair of penalties to Carolina sparked a near-game-winning comeback effort for the Flyers.
Just 3:33 into the third Joel Farabee, like Cates, put home a second chance in front of Andersen to tie the contest. Then, 2:17 later, an attempted playing of the puck by Andersen was knocked down by an attacking Flyer and sent in front for the go-ahead slam dunk.
The outlook was grim for Carolina, who entered the day 30-1-4 when leading after two periods.
However, with the extra attacker on, a penalty to Philadelphia then gave Carolina an offensive zone draw with seven seconds on the clock.
Rod Brind'Amour drew up a play, and it worked.
With 0.3 seconds remaining in regulation, Martin Necas stuffed one home at the side of the net to improbably force overtime.
For the 20th time in 68 games this season, the Canes needed three-on-three, tieing Anaheim and Calgary for the league lead once again.
But during the extra session, only 28 seconds was needed.
Sebastian Aho took Tony DeAngelo one-on-one, and the game were over.
