Contracts have not yet been signed, but the bout will take place on Nov. 21 in Las Vegas once it’s official. It’s good timing for the 125-pound contender fight, as the UFC 255 pay-per-view event features flyweight champion Valentina Shevchenko defending her title against Jennifer Maia in the co-main event.
Chookagian (14-4) is coming off a knockout loss to former strawweight champion Jessica Andrade on Oct. 17 in Abu Dhabi. Despite the loss, Chookagian is still the No. 2-ranked flyweight in the world per the UFC rankings, behind No. 1-ranked Andrade.
The 31-year-old Chookagian fought Shevchenko for the title in February, and came up short via third-round TKO. The fight against Calvillo will mark her fourth appearance in 2020.
Calvillo (9-1-1) catapulted herself into flyweight title contendership with a five-round decision over former title challenger Jessica Eye in June. That was Calvillo’s flyweight debut in the UFC. She accumulated a 5-1-1 record as a strawweight prior to the move up in weight in June.
Calvillo was scheduled to face Lauren Murphy last month, but was forced to withdraw due to a positive COVID-19 test.
