Castillo, a 25-year-old Mexican contender, holds a professional record of 22-1-1 with 14 knockouts. However, because he is not currently rated by the WBO at 105 pounds, the sanctioning body must first determine whether he can be added to its rankings before approving the championship bout.
In a statement released Tuesday, WBO president Gustavo Olivieri explained that the organization’s Ratings and Championship Committee will meet on Wednesday morning to review the request.
“The Ratings and Championship Committee will convene tomorrow morning to carefully evaluate the request, the relevant factual circumstances, and the merits of the athlete,” Olivieri wrote. “Upon completion of its review, the Committee will render the appropriate ruling.”
Collazo had originally been scheduled to defend his WBO title against Canoy in what many viewed as one of the most compelling fights in the minimumweight division. Canoy’s inability to secure a work visa forced promoters to quickly search for a replacement in an effort to keep the champion on the card.
Castillo previously challenged for a world title in 2024, losing a unanimous decision to then-WBA minimumweight champion Knockout CP Freshmart. Since that defeat, the Mexican has rebuilt momentum with several victories, putting himself back into the conversation at world level.
Collazo, 29, unified the WBO and WBA minimumweight titles with a seventh-round stoppage victory over Thammanoon Niyomtrong in November 2025. The Puerto Rican southpaw is regarded as one of boxing’s top fighters below the major weight classes and is aiming to continue his run toward further unification bouts.
If approved by the WBO committee, Castillo would have just days to prepare for the biggest opportunity of his career.
