Holloway scored one of the best knockouts in UFC history in the final seconds of his title fight.

The former featherweight champion was controlling the fight the entire night, but pointed at the floor to challenge Gaethje to exchange blows for the final ten seconds of the bout.

Gaethje, with nothing to lose, accepted the challenge and the two fighters started trading vicious blows.

Holloway still came out on top though, landing a ferocious overhand right which sent Gaetje faceplanting into the floor.

Kansas City Chiefs quarterback Patrick Mahomes was keeping an eye on the fight and had to share his thoughts after the crazy knockout.

“That was crazy!!!!!!!!” he posted on X.

ESPN analyst Robert Griffin III was in attendance for the knockout and posted a video of him and his wife with their jaws dropped while the crowd celebrated around them.

“Ohhhhhh myyyyy GAWD!!!!!!” he captioned the X post.

Fans agreed with Griffin and Mahomes’ reactions, and shared their thoughts in the comments of their posts.

“Great fight awesome ending. You can’t get that from Boxing,” one fan said.

“Mahomes and Max have that clutch gene,” another fan said.

“Best ending to a fight ever!” a third fan said.

“That may be the most awesome moment in UFC history holy crap!!!” a fourth fan said.

Holloway called out reigning featherweight champion Ilia Topuria after the stunning win on Saturday night.

Topuria took the belt from Alexander Volkanovski with a win in February.

If Holloway and Topuria match up for the title, the bout would likely take place later in 2024.
