At UFC 327, held at Kaseya Center in Miami, Florida, Carlos Ulberg defeated Jiri Prochazka with a knockout at 3:45 of the first round, capturing the vacant light heavyweight championship.

Prochazka, who had been on a two-fight winning streak, faced Ulberg, who entered the octagon with an impressive nine-fight winning streak. The fight began with Ulberg landing effective leg kicks, but he appeared to injure his right leg during the bout. Despite this, Ulberg managed to counter Prochazka's advances effectively and landed a decisive check hook that sent Prochazka to the canvas. Ulberg quickly capitalized on the opportunity, finishing the fight with hammer fists on the ground, thus becoming the new champion in the light heavyweight division.
