One of the most anticipated fights in recent UFC history is finally set to happen as Conor McGregor returns to the Octagon to face Max Holloway in the main event of UFC 329. The welterweight showdown marks McGregor’s first fight in five years and revisits a rivalry that began more than a decade ago.
The rematch carries enormous significance for both fighters. McGregor is attempting to prove he can still compete at the highest level after multiple injuries and a lengthy absence, while Holloway enters the contest determined to avenge his only loss to the Irish superstar and strengthen his legacy across multiple weight classes.
Big Return
Conor McGregor’s comeback has been one of the biggest talking points in mixed martial arts.
The former two-division UFC champion has not competed since July 2021, when he suffered a broken leg during his trilogy fight against Dustin Poirier. Since then, injuries, rehabilitation, and several postponed comeback plans kept him away from active competition.
Now 37 years old, McGregor says he is ready for one final push as he prepares to headline UFC 329 at T-Mobile Arena in Las Vegas.
Old Rivalry
This fight marks the second meeting between McGregor and Max Holloway.
Their first encounter took place in August 2013 at featherweight, when McGregor earned a unanimous decision victory despite suffering a knee injury during the bout. At the time, Holloway was still an emerging prospect, while McGregor was rapidly becoming one of the UFC’s biggest stars.
More than a decade later, both fighters return with far greater experience and completely different careers behind them.
Different Paths
Although the rivalry resumes, the careers of the two athletes have followed very different directions.
McGregor has fought only three times since 2018 due to injuries and extended periods away from competition.
Holloway, meanwhile, has remained one of the UFC’s most active elite fighters. He defended championships, headlined numerous events, and consistently faced the sport’s toughest opponents.
His most recent setback came against Ilia Topuria in 2024, marking only the first knockout loss of his professional career.
New Weight
Unlike their first meeting at featherweight, UFC 329 will take place in the welterweight division.
The higher weight class changes the dynamics of the matchup considerably. Holloway is moving well above his longtime featherweight division, while McGregor has previously competed successfully at welterweight.
The additional size may benefit McGregor’s punching power, while Holloway’s cardio and striking volume remain among his greatest strengths.
How each athlete adapts to 170 pounds could play a major role in determining the outcome.
Mendes Reacts
Former UFC title challenger Chad Mendes admitted he never expected McGregor to fight again.
Speaking ahead of UFC 329, Mendes said McGregor had already achieved financial security, worldwide fame, and championship success, making another comeback seem unnecessary.
However, he also acknowledged his excitement now that the fight is officially scheduled, calling it one of the most intriguing matchups of the year.
Comeback Challenge
Mendes also discussed the challenges athletes face after long layoffs.
According to the former contender, extended time away from elite competition naturally affects speed, timing, reaction time, and overall athletic performance.
At the same time, he believes experienced competitors with strong discipline can regain much of their previous form through dedicated preparation.
For McGregor, the biggest question is whether five years away from competition will affect his performance inside the Octagon.
Keys to Victory
Analysts believe each fighter possesses clear advantages.
McGregor remains one of the hardest punchers in UFC history, capable of ending fights with a single clean strike. Holloway, on the other hand, is known for exceptional endurance, high-volume striking, and remarkable durability.
Statistics also highlight another possible factor.
During their first meeting, McGregor successfully mixed striking with wrestling by landing multiple takedowns. Historical UFC data shows Holloway has experienced greater difficulty in bouts where opponents repeatedly take him to the ground.
Whether McGregor chooses a similar strategy could become one of the fight’s biggest tactical storylines.
Prediction Debate
Experts remain divided over the likely outcome.
Chad Mendes believes the betting odds underestimate McGregor’s chances but ultimately predicts Holloway will earn a stoppage victory.
Other analysts point to McGregor’s long absence as the greatest uncertainty. Supporters believe his power and experience can overcome the inactivity, while critics question whether he can perform at championship level after several injury-plagued years.
The uncertainty surrounding McGregor’s condition has become one of the event’s biggest attractions.
What’s at Stake?
The result could significantly influence both fighters’ futures.
A victory for McGregor would represent one of the most remarkable comebacks in recent UFC history and instantly place him back among the sport’s biggest contenders.
For Holloway, defeating one of the UFC’s most recognizable athletes would erase the only loss between them while strengthening his case as one of the greatest featherweights ever to compete, even while moving up in weight.
The stakes extend well beyond a single victory.
Final Thoughts
UFC 329 promises to deliver one of the year’s most anticipated mixed martial arts events as Conor McGregor returns after a five-year absence to face Max Holloway in a welterweight rematch. Their first meeting in 2013 launched two legendary careers, but this contest arrives under very different circumstances. McGregor seeks to prove he can still compete among the sport’s elite despite years away from competition, while Holloway hopes to capitalize on his activity, durability, and experience. Regardless of the result, the main event is expected to draw global attention as two of the UFC’s biggest stars meet once again inside the Octagon.
