Lone’er Kavanagh delivered a seismic jolt to the flyweight division with a unanimous decision victory over former two-time UFC flyweight champion Brandon Moreno in the UFC Fight Night 268 main event in Mexico City.
Kavanagh, stepping in on short notice after Asu Almabayev withdrew because of a hand injury, was widely viewed as an underdog before entering Arena CDMX. Yet the 26-year-old English prospect, with a 10-1 record, seized the moment. From the outset, he set the tone by targeting Moreno’s lead leg with heavy calf kicks. As the fight wore on, Moreno’s movement diminished visibly, blood streaming from a cut opened by Kavanagh’s crisp boxing and precision counters.
Through five rounds, Moreno tried to grapple his way back, seeking takedowns and clinch control. Kavanagh’s takedown defense stood firm, blocking at least six attempts and quickly returning to his feet in the rare moments Moreno got the fight to the mat. Kavanagh consistently answered with volume and accuracy, using the jab to disrupt Moreno’s entries while continuing to punish the legs.

By the fourth round, Moreno was noticeably compromised, hampered by the cumulative effect of Kavanagh’s attacks. Despite sporadic bursts in the clinch with knees and upper-body pressure, Moreno never managed to swing momentum in his favor. Kavanagh, meanwhile, showed composure far beyond his main-event experience, controlling the tempo and rhythm throughout the bout.
All three judges scored the fight for Kavanagh: 49-46, 48-47, and 48-47. His game plan and in-cage poise translated into a comprehensive victory, something few anticipated given the late notice and the former champion’s home-crowd advantage. UFC officials recognized the performance with a $100,000 “Performance of the Night” bonus.
In his post-fight interview with Michael Bisping, Lone’er noted the significance of his opponent, saying “These are the moments I live for, legendary moments… Brandon is a legend… I watched him as a kid.”
Kavanagh’s journey has taken him from the European circuit to Cage Warriors, then to a successful Dana White’s Contender Series bid. He posted solid victories in the UFC against Jose Ochoa and Felipe dos Santos before a knockout loss to Charles Johnson in August 2025. The win in Mexico City erases doubts from that setback, instantly vaulting him into the conversation with fellow emerging contenders like Joshua Van and Tatsuro Taira.
Moreno, once seen as the division’s mainstay and a national hero, has now lost four of his last six. After dropping his title to Alexandre Pantoja and suffering a knockout loss to Taira in December 2025, momentum has continued to slip for the Mexican star. While he remains one of the sport’s most popular figures in his homeland, new questions now surround his standing in the division.
Kavanagh’s victory highlights the evolving landscape at flyweight, shaking up established hierarchies and introducing a fresh challenger to the mix. Observers noted the scale of the upset and the way Kavanagh’s skill set announced his arrival among the elite. The Mexico City card will likely be remembered for how an unheralded English prospect stunned a fan favorite on a week’s notice.
