The ruckus continous a bizarre career stretch for Gamboa. A December 17 bout against Malcolm Klassen was cancelled the day of when a police hotel raid found Klassen in possession of performance-enhancing drugs. Gamboa’s trainer, Ismael Salas, also ditched his fighter the week of the fight after discovering Gamboa was also training with Pedro Diaz.
Gamboa’s last fight was a unanimous decision win over Hylon Williams in December 2015.
