The World Boxing Organization has issued their resolution on the world title reign of John Riel Casimero, who will continue to hold the WBO championship at bantamweight.

A few weeks ago, the WBO ordered Casimero to “Show Cause” on why the bantamweight belt should not be declared vacant.

He was scheduled to make a mandatory defense against Paul Butler on Saturday, December 11, in Dubai.

On the day of the official weigh-in, Casimero withdrew from the fight - indicating that he was very sick. 

The WBO gave him 10 days to submit a medical certification by the hospital institution where he was admitted for medical treatment. He was also ordered to provide his medical records.

Casimero's handlers complied with the WBO's order and supplied the necessary documentation, which the sanctioning body examined and deemed adequate.

Probellum, who promote Butler and hold the promotional rights to the mandatory fight with Casimero, have been given 15 days to advise the WBO whether they plan to reschedule the bout - in order to proceed with the corresponding sanction approval process.

The sanctioning body also laid down some ground rules for the mandatory fight.

In the event that Casimero does not attend the official weigh-in for any reason whatsoever, the WBO title will be declared vacant.

In the event that Casimero is injured or suffers an injury, refuses to fight, or is unavailable to participate, fight, or engage for any reason whatsoever, the WBO title will be declared vacant, and Casimero shall be rated in the WBO bantamweight ratings per the ABC and WBO rating criteria.

In the event that Butler does not attend the official weigh-in for any reason whatsoever, the WBO will withdraw his mandatory challenger status designation and proceed to select the first available contender in the WBO bantamweight rankings.

In the event that Butler is injured or suffers an injury and depending on the type of injury and recovery period, or is unavailable to participate, refuses to fight, or engage for any reason whatsoever, the WBO will withdraw his mandatory challenger status and proceed to select the first available contender in the WBO bantamweight division.
