The president of the World Boxing Council, Mauricio Sulaimán, has revealed that his organization has ordered their flyweight champion, Julio Cesar 'Rey' Martinez, to make a mandatory defense against the Puerto Rican contender McWilliams Arroyo.

Martinez and Arroyo have until February 5th to reach an agreement - or the sanctioning body will order a purse bid.

Sulaiman spoke to ESPN Deportes, and advised the outlet that Martinez is already due to make a mandatory defense and the highest ranked contender is Arroyo of Puerto Rico. He was scheduled to face Martinez last August, but due to a medical setback the champion was forced to withdraw from the fight.

Martinez (17-1, 13 knockouts) was last seen in the ring in October, when he defeated Moisés 'Taz' Calleros. He also saw action in February, when he won a hard-fought decision over unbeaten challenger Jay Harris on the Mikey Garcia vs. Jessie Vargas undercard in Texas.

Because of a non-COVID illness, Martinez was unable to fight Francisco 'Chihuas' Rodríguez in December - in a fight that was booked to be part of the undercard to Canelo Alvarez vs. Callum Smith.

Arroyo (20-4, 15 KO's) has not fought since December 2019, when he defeated Juan Medina. He's put together a three fight win streak after losing to pound-for-pound fighter and super flyweight champion, Kazuto Ioka in September of 2018.
