UFC 327 results: Carlos Ulberg scores stunning KO of Jiri Prochazka to claim title after suffering injury

Ulberg said he suffered a knee injury early in the fight but overcame the issue to score the biggest win of his career

MIAMI -- Carlos Ulberg shouldn't have won, but somehow he did. Not because he wasn't good enough, but because he was fighting on one leg. Ulberg blew out his knee minutes into the main event of UFC 327 on Saturday, yet managed to knock out Jiri Prochazka to win the light heavyweight title. 

It seemed nothing would deter Ulberg on this night. Early in the fight, Ulberg suffered a leg injury that terribly compromised his movement. Everything from Prochazka's kicks to simply taking a step seemed to hurt him. Ulberg's condition was most visible when his leg buckled on an attempted head kick. 

Yet as Prochazka advanced, smelling blood in the water, he walked right into Ulberg's signature left hook. It's the New Zealand fighter's best punch, reminiscent of the one Alex Pereira used to knock out Prochazka. The native of Czechia, functioning on autopilot, tried in vain to grapple with Ulberg. Ulberg came down with Thor's hammer, landing nasty ground strikes that separated Prochazka from consciousness.

"You cannot hunt what you cannot kill," Ulberg said in his post-fight interview, confirming that he blew out his knee.

No one seemed more upset with Ulberg's injury than Prochazka. The former champion, fighting for the vacant title, looked visibly upset once he realized Ulberg was injured. He initially took his foot off the gas before recommencing leg strikes and former pressure. Post-fight, he told Joe Rogan that he regrettably showed mercy and lowered his guard.  

"It was in my hands, and I left him because I saw his injury," Prochazka said. "F--- man. This is one of the biggest lessons in my life. ... I will be back."

Elsewhere on the card, Paulo Costa scored a thrilling knockout of Azamat Murzakanov in a fight he needed to win. Costa rallied to land a devastating head kick that put Murzakanov on the back foot. A quick stumble then led to a complete fall down as the referee waved off the action. It was Costa's first knockout win since 2018

Plus, Josh Hokit made a name for himself in a featured win over Curtis Blaydes. The two authored an all-time great heavyweight fight as they threw caution to the wind and combined to land a record number of strikes over 15 minutes. Hokit quickly parlayed the win over Blaydes into a spot on the White House at Freedom 250 against Derrick Lewis in a fight that was booked immediately after the bout ended.

Ulberg now joins former middleweight champion Israel Adesanya as UFC champions representing City Kickboxing. He also became the first person other than Pereira to beat Prochazka in the UFC.

"The Eraser" is an elite light heavyweight. Costa should be ranked in two divisions come Monday after his successful 205-pound appearance. Costa turned on the heat in Round 3, leaning on his patented power kick. Costa has always performed well against southpaws. Tonight was no exception. Costa used his trademark power kick to blast Murzakanov to the body. In Round 3, he switched things up and targeted the head.
