Rafael Espinoza will defend his WBO featherweight title against Arnold Khegai on November 15 in San Luis Potosi, Mexico.

The event is co-promoted by Zanfer and Top Rank, and the show will be distributed across ESPN Deportes, ESPN Knockout, and TV Azteca.

Some of the other key fights for the event have already been set.

The Ring has learned that heavyweight contender Richard Torrez (13-0, 11 KOs) will take on Tomas Salek (23-7, 14 KOs), while fast-rising junior welterweight prospect Emiliano Vargas (15-0, 13 KOs) will face Jonathan Montrel (19-3, 13 KOs).

Torrez, a 26-year-old southpaw and 2020 Olympic silver medalist for the United States, last fought in April and scored a 10-round unanimous decision win against Guido Vianello. The win has already aged well, as Vianello stopped the previously unbeaten Alexis Barriere in five rounds over the weekend.

The 21-year-old Vargas hasn’t fought since his first-round knockout of Alexander Espinoza in May. The son of Fernando Vargas has fought three times this year and stopped each opponent in a total of five rounds of work.

Also set to be featured on the card are Mexican contenders Jorge Ascanio (14-1-1, 9 KOs) and Jonathan Fierro (22-1, 17 KOs) against opponents still to be determined.

Additionally, as reported by The Ring last month, an IBF 140-pound title eliminator between Lindolfo Delgado (23-0, 16 KOs) and Gabriel Gollaz Valenzuela (31-4-1, 17 KOs) will also be featured on the card.
