Lone'er Kavanagh delivered a career-best performance at UFC Mexico, securing a decision victory over two-time flyweight champion Brandon Moreno. Kavanagh seized a last-minute opportunity to compete and has now firmly established himself within the top 10 of his division. The victory positions him for a significant step up in competition as matchmakers consider his next opponent. The event also featured notable performances from David Martinez, who defeated Marlon Vera in the co-main event, and King Green, who scored a shocking knockout of Daniel Zellhuber.
Lone'er Kavanagh pulled off one of the year's biggest upsets at UFC Mexico on March 3, 2026, defeating two-time flyweight champion Brandon Moreno by decision in the main event after stepping in on short notice to claim the opportunity.
Moreno, ranked second in the flyweight division, entered the contest with a record of 23-10-2 and the reputation of a former titleholder who had headlined marquee events throughout his career. The 32-year-old Mexican, who fights out of Fortis MMA, averages 3.84 significant strikes per minute and lands at 44 percent accuracy, while also threatening consistently on the mat with 1.36 takedowns per 15 minutes. The loss is a significant setback for a fighter widely regarded as one of flyweight's elite.
Kavanagh, who seized a last-minute replacement slot, delivered what the event summary describes as a career-best performance and now sits firmly inside the flyweight top 10. Matchmakers are already considering his next opponent as the win signals a clear step up in competition.
In the co-main event, David Martinez defeated Marlon Vera, the seventh-ranked bantamweight. Vera, a 33-year-old Ecuadorian fighting out of Team Oyama, carries a record of 23-12-1 and is among the more active strikers in the division, landing 4.18 significant strikes per minute at 47 percent accuracy. The defeat adds another obstacle to his path back toward title contention.
Earlier on the card, King Green produced a stunning knockout of Daniel Zellhuber, the 26-year-old Mexican prospect known as "Golden Boy." Fighting out of Xtreme Couture, Zellhuber held a record of 15-4-0 and a six-foot-one frame with a 77-inch reach, and had shown an aggressive output of 5.45 significant strikes per minute heading into the bout.
Why it matters
- Kavanagh's decision win over a ranked former champion reshapes the flyweight top 10 overnight
- Moreno's second-ranked standing will almost certainly drop, tightening the divisional picture below the title
- Vera's loss complicates his bantamweight ranking at number seven and may push him further from a title shot
- Zellhuber's knockout defeat raises questions about the trajectory of one of Mexico's more prominent young prospects
