A potential rematch between Conor McGregor and Floyd Mayweather has once again surfaced, with McGregor expressing openness to a second boxing clash. The proposed fight, reportedly targeted for 2027 under the banner of Zuffa Boxing—the promotional arm launched by UFC president Dana White—has generated buzz, but no concrete steps have been taken. There is no signed contract, no event date, no venue, no weight class, no broadcast deal, and no formal announcement from Zuffa Boxing. The conversation remains speculative, fueled by the immense success of their first encounter in 2017.

The Context of the Rematch Talks

McGregor first mentioned the possibility of a rematch ahead of his return to the UFC at UFC 329 on July 11, 2026. In an interview with TMZ Sports, the Irishman stated that discussions with Mayweather had continued over the years and that he would be ready to step into the boxing ring again. However, the timing of any such fight is now uncertain after McGregor's disastrous return to MMA ended in just 69 seconds. Facing Max Holloway at welterweight, McGregor threw an early jumping kick, landed awkwardly on his right leg, and appeared to injure his knee. Referee Mike Beltran stopped the bout at 1:09 of the first round, awarding Holloway a TKO victory due to injury.

This marked McGregor's first fight in over five years, following his leg break in the trilogy with Dustin Poirier in 2021 and a lengthy recovery. The immediate diagnosis from UFC medical staff, as relayed by Dana White, was a possible torn ACL. McGregor has since confirmed he will undergo surgery, complete rehabilitation, and then fulfill the final fight of his current UFC contract. His coach, John Kavanagh, noted that the knee had not been an issue during training camp, adding an element of unpredictability to the injury.

Zuffa Boxing’s Role in the Potential Event

Zuffa Boxing, launched by Dana White in January 2026, is a logical commercial avenue for a Mayweather-McGregor rematch. The promotion operates under a UFC-style model, with structured ranking systems and regular event schedules. Since its inception, Zuffa Boxing has signed several notable names and expanded its calendar, but neither Mayweather nor McGregor has been announced as part of its roster. White has expressed interest in hosting major crossover events, and a rematch of the 2017 super-fight would undoubtedly be the biggest test of the promotion's drawing power. However, both fighters remain independent assets, and any negotiations would require careful coordination with the UFC and Mayweather’s team.

The First Fight: A Historic Spectacle

The original Mayweather-McGregor bout took place on August 26, 2017, at the T-Mobile Arena in Las Vegas. Mayweather, then 40 years old, stopped McGregor in the 10th round, handing the Irishman his first professional boxing loss. Despite McGregor’s inexperience in the squared circle, the fight was a massive commercial success. The live gate reached $55.4 million from 13,094 paid tickets, placing it among the highest-grossing boxing events in Las Vegas history. The pay-per-view numbers shattered records, with an estimated 4.3 million buys in the United States alone. The event transcended combat sports, drawing attention from mainstream media and casual fans worldwide.

McGregor’s performance that night exceeded many expectations. He won the early rounds by using his reach and awkward timing, but Mayweather’s experience and conditioning took over as the fight progressed. The stoppage came at 1:05 of round ten, after a flurry of punches forced referee Robert Byrd to step in. Mayweather improved to 50-0, surpassing Rocky Marciano’s record, while McGregor returned to the UFC, eventually losing to Khabib Nurmagomedov in 2018.

Challenges for a 2027 Rematch

By 2027, Mayweather will be 50 years old, while McGregor will be 38. The age gap, combined with McGregor’s recent knee injury, presents significant obstacles. Mayweather has not fought a professional boxing match since his exhibition against Logan Paul in 2021, although he has remained active in exhibition bouts and money-spinning tours. McGregor’s injury recovery timeline is uncertain; if he requires ACL reconstruction, rehabilitation could take six to twelve months, pushing his UFC return to late 2027 or beyond. Only after fulfilling his UFC obligation could he consider a boxing match.

Furthermore, the legal and promotional landscape is complex. McGregor is under contract with the UFC, which would likely demand a co-promotion agreement or a significant fee to allow him to box. Mayweather, who traditionally promotes his own events under Mayweather Promotions, would need to align with Zuffa Boxing. Dana White has a history of friction with Mayweather, though both have expressed mutual respect in recent years. The logistics of weight class also remain undefined; the first fight was at 154 pounds, but with both fighters older and heavier, a catchweight might be negotiated.

Career Highlights and Legacy

Conor McGregor’s career is defined by his dual-sport success. He became the first UFC fighter to hold two divisions simultaneously (featherweight and lightweight) in 2016. His boxing venture in 2017, despite a loss, elevated his global fame and net worth. However, his MMA record since then has been spotty: a loss to Khabib, a win over Donald Cerrone, and back-to-back losses to Dustin Poirier (including a leg break). The Holloway fight was meant to be a comeback but ended in injury. McGregor’s legacy as a pioneer of crossover combat sports remains intact, but his fighting future is uncertain.

Floyd Mayweather retired with an undefeated 50-0 record, with wins over Manny Pacquiao, Canelo Alvarez, and Oscar De La Hoya. His defensive mastery and promotional savvy made him the highest-paid athlete of his era. Since retirement, he has engaged in lucrative exhibitions against Logan Paul, Tenshin Nasukawa, and several others, prioritizing entertainment over competition. A rematch with McGregor in 2027 would likely follow the exhibition model, though Mayweather has insisted any fight would be a professional bout under Zuffa Boxing.

Current Status of Talks

Despite the speculation, no formal negotiations have been reported. McGregor’s statement to TMZ was vague, and Mayweather has not publicly commented on the rematch in recent months. Zuffa Boxing has made no announcements regarding either fighter. The injury sustained by McGregor may delay any serious talks until his health is fully assessed. Until then, the rematch remains a topic of conversation among fans and media, driven by the massive success of the first event and the enduring star power of both athletes. Any concrete development would require McGregor’s full recovery, his completion of the UFC contract, and a mutual agreement between all parties involved.

The original fight was a watershed moment for the convergence of MMA and boxing. A second fight, whether under Zuffa Boxing or another banner, would undoubtedly generate enormous interest. But with no signed papers, no date, and a significant injury to overcome, the 2027 rematch is, for now, just a rumor—one that will continue to resurface as long as both fighters remain active in the public eye.
