UFC veteran Jiri Prochazka learned the hard way that there’s nothing more dangerous than a wounded animal.
Prochazka (32-6-1) looked like he was being gifted a victory Saturday against Carlos Ulberg (15-1-0) in the main event of UFC 327 at Kaseya Center in Miami, Fla. Ulberg visibly injured his leg in the first round while the two were on their feet in the middle of the ring.
Watch Ulberg’s right leg ripple as the two were exchanging blows.

Instead of pouncing on his injured opponent, Prochazka proceeded to toy with Ulberg throughout the round. That left an opportunity for Ulberg to clock Prochazka with a wicked left hook that rocked the Czech fighter.
In case you missed it .! Jiri Prochazka couldn’t stop mocking and clowning.

Ulberg won the vacant light heavyweight championship with the TKO of Prochazka, who was a sullen figure as he spoke to Joe Rogan after the match.
“F–k. I felt, like, mercy, you know?” said Prochazka as he looked stunned by the result.
“In that fight, I felt so sorry for him. Man, this is one of the biggest lessons in my life, man. I still can’t understand. That fight was won. I had it, it was in my hand. I just left him because I saw his injury, f–k man. … Life is about that, learn and be better.”

Ulberg confirmed after the fight that he “blew out” his knee and would most likely need surgery. He’ll at least go into his rehab riding the high of a win over one of UFC’s most seasoned light heavyweights.
Prochazka aside, the next biggest loser in all this is the UFC. Prochazka, the crowd favorite during the match, looked poised to take the belt and begin a new light heavyweight title reign. Instead, the lesser-known Ulberg took him out before having to undergo what is expected to be a lengthy recovery himself.
