Uncrowned will provide instant outcomes, blow-by-blow accounts, notable moments, fighter entrances, and schedule details for the Zuffa Boxing 4 event featuring Jai Opetaia against Brandon Glanton, held this Sunday evening at the Meta Apex venue in Las Vegas, Nevada. The marquee bout of the evening features Jai Opetaia challenging Brandon Glanton for the inaugural Zuffa cruiserweight championship.
Opetaia, boasting a perfect record of 29 wins with 23 knockouts, steps into his first Zuffa appearance as an undefeated competitor, widely recognized among the premier cruiserweight talents globally. The Australian left-hander competed thrice in 2025, each time successfully retaining his IBF cruiserweight belt. His most recent triumph was an eighth-round knockout of Huseyin Cinkara last December.
While Opetaia currently holds the IBF cruiserweight championship, that specific title will not be contested this Sunday since the IBF declined to authorize a discretionary defense opposite Glanton. Consequently, Opetaia’s IBF title will be vacated following the conclusion of tonight’s fights.
Glanton, with a record of 21 wins, 3 losses, and 18 knockouts, has experienced defeat on three previous occasions. He suffered his initial professional loss to David Light in December 2022, then encountered another setback against Soslan Asbarov in March 2023. Glanton subsequently secured a sequence of three victories before his defeat by Chris Billam-Smith this past April during the undercard of the Chris Eubank Jr. vs. Conor Benn event in London. He regained his winning form in October, achieving a sixth-round victory over Marcus Browne.
Preliminary bouts for the Opetaia versus Glanton event are scheduled to commence at 6 p.m. ET on Paramount+, while the primary card is set to get underway at 9 p.m. ET, with the featured attraction’s ring entrances anticipated approximately at 11 p.m. ET.
