Prince Naseem Hamed must defend his International Boxing Federation title in his next fight, delaying his chance to unify the four featherweight belts.
Hamed has been ordered by the IBF to fight its leading contender, Mexico's Hector Lizarraga, by Aug. 8. Hamed successfully defended his WBO and IBF titles against Argentine Juan Cabrera Saturday, improving his record to 27-0.
"The IBF are threatening all sorts of things," Hamed promoter Frank Warren said. "but Lizarraga is not a good match. He's lost eight fights and drawn five, and I don't feel comfortable about promoting it."
Hamed and Warren are seeking a fight with WBA champion Wilfredo Vasquez or WBC titlist Luis Espinosa in a bid to unify the belts, instead of taking the IBF matchup.
