The Ultimate Fighting Championship has announced that the Octagon will return to Mexico City for the second time in two years and seventh time overall, headlined by a Top 10 flyweight showdown in UFC Mexico City 2025: Moreno vs. Erceg at the Arena CDMX on March 29, 2025.
In the main event, former UFC flyweight champion and No. 2 ranked contender Brandon Moreno takes on former title challenger and No. 9 ranked Steve Erceg. In the co-main event, recently announced UFC Hall of Famer Kelvin Gastelum faces Joe Pyfer.

Among the most popular athletes on the roster, former UFC flyweight champion Moreno (22-8-2, fighting out of Tijuana, Mexico) plans to impress in his third UFC main event in a row in front of his home crowd.
Moreno has entertained fans with his winning performances against Deiveson Figueiredo (twice), Kai Kara-France and Brandon Royval. He now intends to earn another shot at flyweight gold with a statement performance against Erceg.
A well-rounded competitor who has finished eight of his 12 wins, Erceg (12-3, fighting out of Perth, Western Australia, Australia) aims to prove he can compete with the top of the flyweight division and earn another shot at the championship.
The Aussie Erceg holds notable wins over Matt Schnell, Alessandro Costa and David Dvorak. Erceg now seeks to snatch Moreno's spot in the rankings in dramatic fashion in his first-ever main event.
Recently announced as the newest inductee for the 2025 UFC Hall of Fame for his iconic bout with Israel Adesanya, Gastelum (19-9 1NC, fighting out of Yuma, Ariz.) returns to the Octagon looking to put together another long win streak.
Gastelum has also delivered highlight-reel performances against Michael Bisping, Jacare Souza and Chris Curtis. He now plans to go toe-to-toe with Pyfer and put on a show for the Mexican fans.
Dana White's Contender Series standout Pyfer (13-3, fighting out of Philadelphia, Penn.), on the other hand, looks to start his year with a signature knockout, coming into the Gaestlum fight on the back of a first-round stoppage.
A dynamic finisher, he has ended 12 of his 13 victories before the final bell, including those over Marc-Andre Barriault, Gerald Meerschaert and Alen Amedovski. Pyfer now has his sights set on breaking into the Top 15 by becoming the first person to KO Gastelum.
