Following days of confusion, the IBF has decided not to sanction Jai Opetaia’s Zuffa Boxing debut against Brandon Glanton at the UFC Apex in Las Vegas on Sunday.
Opetaia (29-0, 23 KOs) had said yesterday in an interview with Sporting News Australia: “We got the email today. We are fighting for the IBF as well. They are on board, they are keen to be a part of it.”
The Australian southpaw’s interview followed mixed signals in the fight-week build-up against Glanton. Opetaia came to the face-to-face on Thursday without the IBF title around his shoulder, only displaying his Ring Magazine title. Then at yesterday’s press conference, the red and gold belt was front and center for the cameras to see, but there was no acknowledgement of the IBF title as Opetaia entered the stage. “The Ring Magazine cruiserweight champion,” was how Zuffa Boxing’s first major signing was announced.
ESPN Knockout had reported the day earlier that the IBF were not going to allow Opetaia to defend his title if he were to also fight for the inaugural Zuffa world cruiserweight title. However, just hours ago the IBF released the following statement:
“The International Boxing Federation (IBF) has withdrawn sanction of the optional defense of the IBF Cruiserweight Title between champion Jai Opetaia and #15 ranked contender Brandon Glanton scheduled for March 8, 2026.
“The initial sanction followed discussions that began on February 11, when IBF President Daryl Peoples, after learning about the contest on social media, reminded Opetaia’s representatives of IBF Rule 5 governing champions and unification bouts. After continued dialogue, on March 3, Opetaia’s team confirmed the fight would not be a unification and that any belt awarded by Zuffa would be ‘characterized as a trophy or token of recognition.’ The IBF has not had any discussion regarding this bout with any direct representative from Zuffa Boxing. However, the organization received assurances from Opetaia’s representatives that this would be the case. The IBF approved the bout under these conditions as the bout would no longer conflict with IBF Rule 5.E.2, which states in part – ‘For the purpose of unification of titles, the preeminent champions of the World Boxing Association (“WBA”), the World Boxing Council (“WBC”), and the World Boxing Organization (“WBO”) may be designated as “elite contenders” and may be permitted to fight for the unified title.’”
The statement from the governing body also stated that it plans to strip Opetaia when he fights for the first Zuffa world title.
“With sanction withdrawn, the Opetaia vs. Glanton bout is now an Unsanctioned Contest. IBF Rule 5.H. states in part – ‘An Unsanctioned Contest is a fight which the IBF has not formally approved for sanction or where sanction has been formally withdrawn. If a Champion participates in an unsanctioned contest within his prescribed weight limit, the title will be declared vacant whether the Champion wins or loses the bout.’”
“The organization’s rules don’t always yield the preferred or popular outcome, but they provide structure and transparency, serving not just the champion but also those waiting for the opportunity to fight for the title. The pursuit of undisputed status – by unifying the IBF, WBA, WBC, and WBO titles – represents the highest ambition in the sport.”
Opetaia and Zuffa announced their collaboration with a message of becoming “undisputed.” But for the man largely recognized as the best cruiserweight on the planet, he appears to be losing his recognized world title he has already lost once before.
