Arely Mucino is going on the defensive…

The 34-year-old Mexican professional boxer and reigning IBF flyweight champion will make the first defense of her title against Mexican American fighter Gabriela Fundora on October 21 at the Kia Forum in Inglewood, California, according to ESPN.

Mucino, ESPN’s No. 2 flyweight, last fought in October when she beat Leonela Paola Yudica for the IBF title. Mucino (32-3-2, 11 KO) had been the WBO and WBC flyweight champion at points earlier in her career.

Her last loss came in 2015 by unanimous decision to Yessica Chavez. Mucino has won her past 11 fights.

Fundora, ESPN’s No. 5 flyweight, has been one of ESPN’s top prospects the past two years. The 21-year-old last fought in April, beating Maria Micheo Santizo by unanimous decision.

This will be the third fight this year and first title shot for Fundora (11-0, 4 KO), who is from California and is the younger sister of super middleweight Sebastian Fundora.
