Mark Magsayo will face Andres Cortes in a 10-round lightweight bout on the Ryan Garcia vs. Conor Benn card on September 12, and the fight will open the main card at T-Mobile Arena in Las Vegas. The matchup puts a former world champion into a high-profile slot on one of the promotion’s biggest nights.
The addition gives Garcia Vs Benn a new selling point beyond the welterweight main event and the cruiserweight co-feature. Both fighters are under the Zuffa banner, so the bout also fits the card’s structure: a promotion-driven showcase built around its own names, with Magsayo and Cortes handed the first spot after the top two attractions.
Magsayo enters with a 29-2 record and 19 KOs, and he already showed he can carry his new weight when he beat Feargal McCrory at lightweight in his previous appearance. Most of his career was spent at featherweight, where he reached the top in January 2022 by defeating Gary Russell Jr. for the WBC title before losing that belt to Rey Vargas six months later. The move to 135 has now become more than an experiment; it is the weight at which he is being asked to matter on a major card.
Cortes, meanwhile, brings a perfect 25-0 mark with 13 KOs, but the unbeaten record does not tell the whole story. He fought Eridson Garcia and Abraham Nova in difficult recent outings, and that is the kind of detail that keeps a matchup interesting even when the numbers look clean. He also comes in after time under the Top Rank banner and after beating Garcia in April on a Zuffa card, so there is a line to follow from his old stage to this one.
The fight was first reported on August 5 as a deal being finalized, and the announcement now confirms where it sits on the card: not as filler, but as the first bout fans will see once the main show begins. That placement matters because it suggests the card is built to move quickly from the opening bell into the stronger names, with Ryan Garcia vs. Conor Benn in the welterweight main event and Jai Opetaia vs. Noel Mikaelian in the cruiserweight co-feature still to come. What remains less clear is why Magsayo and Cortes were matched to lead the main card, a question that the records explain only partly and the styles will have to answer in the ring.
