IBF steps back as Opetaia-Glanton bout becomes unsanctioned amid undisputed chase

The IBF withdrew sanction for Jai Opetaia vs. Brandon Glanton, making Sunday’s bout an unsanctioned contest even though the Ring Magazine title and the new Zuffa cruiserweight belt remain involved; the IBF title could be vacated if the fight proceeds without sanctioning, opening a path to a vacant title for contenders like Billam-Smith or Masson, while Opetaia’s goal of undisputed status continues to hinge on future unifications and defenses.
