Polish professional boxer and Klitschko-era title challenger
Usyk has vacated the WBA, WBC and IBF heavyweight belts to allow contenders to fight for them, a move that opens the division and sets the stage for new champions. Kabayel has become WBC champion, while Gassiev is poised to inherit the WBA title; IBF actions point toward Frank Sanchez or Moses Itauma as next contenders. The sport faces a reshuffle as Usyk pivots toward a final, high-stakes bout.
