Uncrowned has Jai Opetaia vs. Brandon Glanton live results, round-by-round updates, highlights, ring walks and start time for the Zuffa Boxing 4 fight card on Sunday night at the Meta Apex in Las Vegas, Nevada. In the night's main event, Jai Opetaia takes on Brandon Glanton with the inaugural Zuffa cruiserweight title up for grabs.

Opetaia (29-0, 23 KOs) enters his Zuffa debut unbeaten and widely regarded as one of the best cruiserweights in the world. The Australian southpaw fought three times in 2025, successfully defending his IBF cruiserweight title each time. Most recently, he knocked out Huseyin Cinkara in Round 8 this past December.

Opetaia is the reigning IBF cruiserweight champion, although the belt is not on the line Sunday because the IBF refused to sanction a voluntary defense against Glanton. Opetaia will be stripped of his IBF title after tonight.

Glanton (21-3, 18 KOs) has been defeated three times prior. He lost his unbeaten record to David Light in December 2022 and followed it with another defeat at the hands of Soslan Asbarov in March 2023. Glanton put together a three-fight win streak before losing to Chris Billam-Smith this past April on the Chris Eubank Jr. vs. Conor Benn undercard in London. Glanton returned to his winning ways in October with a sixth-round win over Marcus Browne
