John Riel Casimero seemingly opened a lot of doors to lucrative opportunities after not only successfully defending his WBO bantamweight belt and winning his fifth straight title bout, but also adding Guillermo Rigondeaux’s name to his resume.
The Filipino boxing star looked to be on his way to big things, but like many stories in boxing, some questionable behavior along with serious management issues derailed all of that.
An all-Filipino title bout against Nonito Donaire was set, but some ugly remarks Casimero and his team directed towards his opponent’s wife (and manager) cost him that payday.
