Former IBF junior featherweight world champion Steve Molitor faces a change of opponent for his fight in Ontario on November 21.

Battle-tested Argentine Jose Saez (17-8-4, 8 KO's) steps in for compatriot Sergio Javier Escobar in the co-main event at Rumble at Rama X, in Rama.

The eight-round showdown will be the evening's co-feature before nineteen year-old Filipino sensation Marvin Sonsona (14-0, 12 KO's) defends his WBO junior bantamweight world title for the first time against Mexico City's Alejandro Hernandez (22-7-1, 11 KO's).

Molitor rebounded from his devastating loss last November to unified 122lb world champion Celestino Caballero with a hard-fought split decision over Heriberto Ruiz to capture the IBF's number two ranking, guaranteeing himself a spot in an IBF world title eliminator.

Molitor followed up the win over Ruiz with a convincing fifth-round KO victory over Dario Azuaga at Rumble at Rama IX.
