Answer
IBF, the International Boxing Federation, is the title that Jai Opetaia held before vacating it. The IBF is one of the four major sanctioning bodies in professional boxing, alongside the WBA, WBC, and WBO. Opetaia won the IBF cruiserweight title in August 2022 by defeating Mairis Briedis, but he later vacated the belt in order to pursue a fight against undisputed light heavyweight champion Artur Beterbiev.
