Jai Opetaia's long-awaited world-title defence has copped a further delay, the Australian champion blasting Mateusz Masternak for "wasting his time" after the mandatory challenger's last-minute refusal to fight.
Gold Coast-based Opetaia hasn't fought since his stoic upset of Mairis Briedis last July, when he endured 10 rounds with a badly broken jaw to claim the IBF and The Ring cruiserweight belts in one of the fights of the year.
