Alex Pereira knocks out Jiri Prochazka: UFC 303 results, highlights

UFC 303 was supposed to mark Conor McGregor's return to the octagon. But his highly-anticipated bout against Michael Chandler was scuttled (for now) due to an injury McGregor suffered in the lead-up to the fight.

But credit the UFC, which moved swiftly to replace the main event and salvage a pay-per-view card that suffered a few other setbacks. And the new main event was plenty exciting for fight fans: Alex Pereira and Jiri Prochazka squaring off again, with the light heavyweight title Pereira won against former champ Prochazka last November on the line.

USA TODAY Sports is here with all the results and top highlights from UFC 303:

Alex Pereira vs. Jiri Prochazka result

And still!!!

Alex Pereira showed why he's perhaps the baddest man in the UFC as he knocked out Jiri Prochazka to retain his light heavyweight title.

This fight started with a stare down for the ages — it gave your humble writer goosebumps! — and then it delivered.

The first round was mostly a feeling out process with the fighters staying on their feet ... that is until Pereira completely leveled Prochazka with a right hand right before the bell. That was just a harbinger of things to come.

Early in the second, Pereira caught Prochazka in the head with his left foot, dropping the former light heavyweight champ. Referee Herb Dean probably could have (should have?) called the fight right then and there, but Pereira jumped on Prochazka for some brutal ground-and-pound that drew the stoppage just 13 seconds in.

While a very wobbly Prochazka was receiving assistance, commentator Daniel Cormier observed that Pereira popped his own toe back into place.

Pereira's TKO victory marks his second successful title defense after he won the then-vacant light heavyweight championship over Prochazka in November 2023.

It's also a win — coming in a main event that only came together after Conor McGregor's toe injury derailed his fight — that further cements Pereira as one of the UFC's brightest stars. Could a run at a third belt at the heavyweight level be next?

Diego Lopes vs. Dan Ige result

Shoutout Dan Ige! Shoutout Diego Lopes! This was an awesome fight — especially considering it wasn't on the card just a few hours ago.

Ige took the fight on extremely short notice after Brian Ortega wasn't able to go and he and Lopes put on a show in a bout fought at a 165-pound catchweight. Though Lopes won a unanimous decision, 29-28 on all three cards, the crowd was clearly appreciative of Ige's effort after coming in to salvage a fight.

The crowd gave a standing ovation after the final bell as the fighters raised their hands together.

The crowd gave another ovation when Ige was interviewed. He said he viewed taking the fight as "an opportunity to become a legend."

"It doesn't matter. Eight weeks? Six weeks? Four weeks? Four hours?! It doesn't matter! This is what I live for! This is my dream. I get to wake up and do what I love," Ige said.

Anthony Smith vs. Roman Dolidze result

This fight arriving on the UFC 303 card was a total odyssey. But fans probably weren't super thrilled with the actual bout — the fans at T-Mobile Arena certainly weren't anyways, as they booed after the final horn.

The most eventful moment of the fight was found in the second round, when Dolidze unloaded some ground-and-pound on a fallen Smith. But otherwise, the bout was fairly dull and Dolidze earned a unanimous decision win (30-27, 29-28, 29-28).

Mayra Bueno Silva vs. Macy Chiasson result

Chiasson opened up a huge cut right above Bueno Silva's eye with a brutal elbow while the pair was on the ground during the second round. The fight was eventually stopped by the ref for a medical evaluation and the ringside doctor called the fight. (Jon Anik relayed that the cut was so deep it was nearly "down to the bone.") Thus, this high-event bout ended in a bloody but anticlimactic finish in favor of Chiasson.

Bueno Silva vehemently protested the decision to stop the fight, even jumping the cage to have a discussion with UFC President Dana White.

Ian Machado Garry vs. Michael Page result

This was a close battle and an interesting clash of styles. Page had the clear striking advantage, but Machado Garry proved to be the superior grappler. In the end, the judges awarded Machado Garry a unanimous decision victory with 29-28 scores across the board.

Machado Garry has yet to lose in his MMA career.

Joe Pyfer vs. Marc-Andre Barriault result

Pyfer just ended the prelims with a bang. He knocked out Barriault with some heavy punches just 1:25 into the fight. Three of the four prelims ended with stoppages. Hopefully the action continues on the main card.

New fight on UFC 303 card: Diego Lopes vs. Dan Ige

Brian Ortega has been scratched from his UFC 303 fight, but his opponent is still set to compete.

Ortega is sick and running a 103-degree fever, Jon Anik relayed on the broadcast. Jeff Mullen of the Nevada State Athletic Commission said on the broadcast Ortega was "medically unable to compete."

Diego Lopes is still hopping into the octagon, though. He will be taking on Dan Ige, who was tapped as a (truly unprecedented) last-minute replacement. Mullen said that Ige is cleared to compete because he's fought recently enough that all his medicals are up to date in the eyes of the commission.

A card that has faced plenty of hurdles has somehow, some way cleared another one.

Cub Swanson vs. Andre Fili result

Fili defeated Swanson in a split decision. Two judges gave the fight to Fili (29-28) while one judge ruled it 29-28 in favor of Swanson.

Charles Jourdain vs. Jean Silva result

Now we're cooking. Jean Silva delivered a second consecutive knockout on this card by dropping Charles Jourdain with a vicious uppercut. It brought the fight to a sudden close at 1:22 of the second round. Silva did miss weight before the fight, however.

Payton Talbott vs. Yanis Ghemmouri result

We have our first stoppage! Payton Talbott proved why he was a massive favorite in this fight, dropping Ghemmouri to the canvas with a brutal right and following it up with strikes that caused the ref to stop the fight just 19 seconds in.

Michelle Waterson-Gomez vs. Gillian Robertson result

Robertson closed out the early prelims with an impressive unanimous decision victory (30-27, 30-27, 30-26). Waterson-Gomez announced her retirement after the bout in an emotional scene. The UFC played a very nice tribute video for her and Waterson-Gomez delivered a heartfelt speech.

Andrei Arlovski vs. Martin Buday result

Not a lot happened in this one. The competitors were implored to be more active multiple times by the ref and were booed when the final horn sounded. The judges ruled it a split decision in Buday's favor (30-27, 29-28 to one 29-28 card for the 45-year-old Arlovski).

Rei Tsuruya vs. Carlos Hernandez result

In a match defined by wild grappling, it was Tsuruya — in his UFC debut — who emerged victorious. He earned a unanimous decision victory with scores of 29-28 on all three scorecards.

Ricky Simon vs. Vinicius Oliveira result

Oliveira and Simon went the distance, with Oliveira securing the victory by unanimous decision (30-27, 30-27, 29-28).

Why Conor McGregor fight isn't on UFC 303 card

Speculation that the McGregor-Chandler fight might be in trouble began when the UFC suddenly called off a June 3 press conference that was set to be staged in Dublin. Ten days later, UFC President Dana White announced the fight was off the 303 card with an injury sidelining McGregor. That injury has since been revealed to be a broken toe.

McGregor last fought in July 2021, when he lost via doctor's stoppage after he broke his leg in a fight against Dustin Poirier.

Alex Pereira vs. Jiri Prochazka: Tale of the tape

Alex Pereira vs. Jiri Prochazka first fight

Alex Pereira defeated Jiri Prochazka by second-round TKO in their battle for the then-vacant light heavyweight championship at UFC 295 in November.

Alex Pereira championship history

Before capturing the light heavyweight title, Pereira — a kickboxing standout — was the middleweight champ. He defeated Israel Adesanya by TKO at UFC 281 in December 2022 to win that belt, but Adesanya got revenge in the rematch at UFC 287 in April 2023 by knocking out Pereira to recapture the title.

Pereira moved up to light heavyweight after the defeat. He has one successful title defense since winning the belt in November, knocking out Jamahal Hill at UFC 300 in April.

Jiri Prochazka championship history

Jiri Prochazka defeated Glover Teixeira via submission at UFC 275 in June 2022 to win the light heavyweight title. But he never got to stage a proper defense, vacating the title due to injury. His next time in the octagon was his loss to Pereira in November 2023.
