mcgregor vs holloway 2: 7 things you need to know before july 11
On July 11, 2026, the biggest name in combat sports history returns to the octagon for the first time in five years. The McGregor vs Holloway 2 fight at UFC 329 is one of the most anticipated rematches in MMA history and one of the most debated. Half the combat sports world thinks Conor McGregor has no business being in that cage. The other half thinks he was born for exactly this moment.
Here is everything you need to know before fight night.
why mcgregor has been gone for 5 years
The McGregor vs Holloway 2 matchup would not exist without understanding why McGregor has been absent from competition since July 2021.
At UFC 264 in Las Vegas, McGregor suffered a gruesome leg break in the first round of his trilogy fight against Dustin Poirier. He had broken his tibia and fibula against the canvas while throwing a kick. The injury ended the fight immediately and required multiple surgeries and a lengthy rehabilitation process that stretched through 2022 and into 2023.
What followed the injury was one of the most turbulent periods of McGregor’s personal and professional life. He faced and settled a civil sexual assault lawsuit in Dublin in 2024. His Proper No. Twelve whiskey brand, which he had sold the majority of in 2021 for a reported $600 million, went through ownership changes. His MMA team SBG Ireland restructured. His relationship with the UFC went through its own complicated negotiations before the McGregor vs Holloway 2 fight was announced.
Through all of it, McGregor maintained publicly that he was coming back. According to ESPN, his return to full training was confirmed by his coaches in late 2025, and the UFC formally announced the fight during UFC Vegas programming in spring 2026.
who max holloway is and why this opponent matters
The McGregor vs Holloway 2 fight is not a tune-up for McGregor’s return. Holloway is arguably the most dangerous striker on the UFC roster.
Since losing his featherweight title to Alexander Volkanovski in 2019, Holloway has been on a sustained run that has made many analysts consider him the most well-rounded fighter in the sport. He won back the featherweight championship. He challenged Islam Makhachev for the lightweight title and pushed the pound-for-pound number one fighter to a grueling five-round decision. He knocked out Justin Gaethje in spectacular fashion to claim the BMF title one of the most celebrated knockouts in recent UFC history.
Holloway has never lost by knockout in his career. His chin is regarded as one of the best in the sport. His volume, pace, and accuracy make him elite at any weight.
The McGregor vs Holloway 2 fight sends both of them into uncharted territory: welterweight, 170 pounds, a division that Holloway has never competed in and that McGregor has only fought in once before, nearly a decade ago.
what happened in their first fight
The McGregor vs Holloway 2 rematch is set 13 years after their original fight.
In August 2013, McGregor and Holloway met at UFC Fight Night: Shogun vs Sonnen in Boston. Neither was famous. McGregor was building his reputation as a rising Irish prospect. Holloway was 21 years old and two years into his UFC career. McGregor won by unanimous decision in a featherweight bout that nobody would have predicted would become the foundation for one of the sport’s most anticipated rematches.
Both fighters look back on that fight as a relic of an earlier era. Holloway has said publicly that he has grown so much as a fighter that the 2013 version of himself and the 2026 version are essentially different athletes. McGregor has expressed similar confidence, stating that the version of himself returning to competition is the best he has ever been.
The McGregor vs Holloway 2 promotional narrative centers on that evolution two fighters who met before the world knew their names, meeting again as legends.
the weight class question
One of the most unusual aspects of the McGregor vs Holloway 2 matchup is the decision to hold it at welterweight.
McGregor has competed at 145 pounds, 155 pounds, and 170 pounds across his career. His only welterweight fight was against Nate Diaz in March 2016, which he won by majority decision. He rematched Diaz at 170 pounds later that year.
Holloway has competed exclusively at featherweight throughout his career. The McGregor vs Holloway 2 fight will be his professional debut at welterweight.
The choice of weight class is unusual because it disadvantages the fighter Holloway who is coming in at the peak of his career. Welterweight fighters are typically larger and stronger than 145-pound featherweights. The question analysts are asking is whether Holloway’s elite skill set translates to the higher weight class, and whether McGregor’s naturally larger frame gives him an advantage he would not have at lighter weights.
what the rest of the fight card looks like
The McGregor vs Holloway 2 main event is surrounded by a card that stands on its own.
In the co-main event, Paddy Pimblett faces Benoit Saint-Denis in a pivotal lightweight matchup. Pimblett has become one of the UFC’s most popular figures globally, and his fights consistently generate enormous social media engagement. Saint-Denis is one of the most dangerous finishers in the division.
Cory Sandhagen vs Mario Bautista rounds out the upper portion of the card at bantamweight, and Robert Whittaker returns at light heavyweight against Nikita Krylov. According to Tapology and ESPN fight center, the full card represents one of the most talent-dense lineups assembled for International Fight Week in recent memory.
why mcgregor’s return is genuinely hard to predict
The McGregor vs Holloway 2 fight has generated more debate than almost any matchup in recent MMA history because of a genuine uncertainty that extends beyond typical fight previews.
Five years is an enormous gap in elite combat sports. The sport has evolved. The athletes McGregor would compete against are operating at a level shaped by those five years of development. McGregor himself is 38 years old and returning from significant injury.
On the other side of that argument, McGregor has consistently defied conventional athletic timelines throughout his career. His power has never been questioned. His ability to generate outcomes with a single punch is as real now as it has ever been. Former training partner Dillon Danis has predicted publicly that McGregor stops Holloway with a knockout.
The odds tell a different story, listing McGregor as a significant underdog for the McGregor vs Holloway 2 fight. But odds have been wrong about McGregor before.
what is actually at stake on july 11
The McGregor vs Holloway 2 fight carries weight beyond the result.
A McGregor victory would be one of the most remarkable comeback stories in sports history and would almost certainly set up another major fight potentially a world title shot or a third meeting with a former rival. A McGregor loss, depending on how it happens, could mark the definitive end of his competitive career at the highest level.
For Holloway, a win over McGregor in McGregor’s return fight would cement his standing as the most versatile and dangerous fighter of his generation. A loss would be a significant setback for a fighter who has been on one of the most sustained elite runs in the sport.
July 11 is twelve days away. International Fight Week in Las Vegas will bring together the largest concentration of MMA fans, media, and industry figures of the year. The McGregor vs Holloway 2 fight is the reason most of them are going.
