The Hogan fan was wearing a jersey of Penguins star Evgeni Malkin and didn't seem to appreciate Hartnell's actions.
Hartnell took to Twitter after the game to poke fun at what happened.
Almost had to give someone Hulksters classic finishing move #Thelegdrop hahahahaahahah. Just kidding.— Scott Hartnell (@Hartsy19) April 1, 2012
It was just another interesting moment in a heated battle between two fierce Pennsylvania rivals. The Flyers won the game, 6-4, but with about a minute left in the game, the two teams engaged in a huge line brawl that even had coaches on both sides barking at each other.
The Flyers are now 4-1 against the Penguins this season, and the two teams will meet for the final time in the regular season on Saturday.
Barring any unforeseen changes to the two team's current position in the Eastern Conference standings, they will play each other in the first round of the Stanley Cup playoffs.
If this is the kind of emotion and action these two rivals will have in the playoffs, then hockey fans everywhere are in for a real treat in just a few weeks time.
