UFC Fight Night Mexico 2026 is set to take place on Saturday, February 28, at the Arena CDMX, starting at 7 PM Local Time in Argentina and Brazil. The main event will feature Mexican idol Brandon Moreno, who is looking to bounce back from a recent defeat and reestablish his position within the flyweight division. He will face Lone’er Kavanagh, a last-minute replacement with under three weeks of preparation for his first main event in the UFC.

Brandon Moreno enters this fight under significant pressure, as he is coming off his first technical knockout loss to Tatsuro Taira at UFC 323. This defeat halted a two-fight winning streak that had placed him back in contention for the title. Originally matched against Asu Almabayev, Moreno's fight plan had to be adjusted due to Almabayev's withdrawal, allowing Kavanagh to step in as a challenger.

The implications of this fight are high for both competitors; for Moreno, a victory could help him regain momentum in his career, while for Kavanagh, this opportunity presents a chance to make a significant impact in the sport, given he has very little preparation time. The fan interest surrounding this main event is expected to be substantial, not only due to Moreno’s popularity in Mexico but also because of the dynamic nature of UFC fights, which continues to attract audiences across Latin America.
