GLORY 42 was held at AccorHotels Arena in Paris, France this season and featured a wild ending between Murthel Groenhart and Harut Grigorian.
Grigorian turned his back to Groenhart in the second round of their fight when Groenhart unleashed a brutal knockout blow.
The shot was completely legal, but still was a bad look for Groenhart.
Then, after the vicious knockout, fans entered the ring and attacked Groenhart while Grigorian was laying unconscious on the other side of the mat. ESPN shared footage of the wild moment.
Glory kickboxing announcer Todd Grisham also shared a photo of the scene:
The attack on Groehart left him injured, with some believing he may have broken his jaw as a result of the punch from the fan.
