Clase y Talento, the Guadalajara-based promotional firm founded by Canelo Alvarez’s trainer Eddy Reynoso, won the promotional rights to promote the rematch between WBC flyweight champion Julio César Martínez and McWilliams Arroyo at a WBC purse bid. Clase y Talento bid $345,000. The purse split will be Martinez 65% / Arroyo 35% with 10% of the total bid reserved to be paid as a bonus to the winner of the fight.

In 2021, Martínez and Arroyo clashed in a contest that prematurely ended in round three being declared a no contest after an accidental clash of heads. Prior to that, both visited the canvas, leaving expectations at the highest level towards this second meeting. Martínez-Arroyo II has been postponed on several occasions due to injuries and other factors suffered by both fighters, but now it will hopefully happen.
