Background

This event was initially planned to take place at Astana Arena in Nur-Sultan, Kazakhstan and would have been the first that the promotion had contested there. However, it was announced by UFC president Dana White on April 9 that starting with UFC 249, all future events were indefinitely postponed due to the COVID-19 pandemic.

While not officially announced by the organization, the promotion was also targeting a bantamweight bout between former WSOF Bantamweight Champion and UFC Bantamweight Championship challenger Marlon Moraes and Petr Yan to serve as the original event headliner. The event is still expected to stream entirely on ESPN+ and a women's flyweight bout between former UFC Women's Flyweight Championship challenger Jessica Eye and Cynthia Calvillo will serve as the new event headliner.

Additionally, the event includes fighters that were pulled from other events previously cancelled, as well as the following bouts:

A middleweight bout between Karl Roberson and Marvin Vettori (originally scheduled for UFC Fight Night: Smith vs. Teixeira, but Roberson pulled out due to issues related to his failed weight cut).
A women's bantamweight bout between Julia Avila and Karol Rosa. The pairing was expected to meet at UFC Fight Night: Maia vs. Askren in October 2019, but Rosa pulled out due to a knee injury. They were later rescheduled for UFC Fight Night: Overeem vs. Harris and UFC Fight Night: Hermansson vs. Weidman, but both times the bout was postponed due to the COVID-19 pandemic. They were later booked for this event, but the bout was cancelled for the fourth time as Rosa had visa issues. She was replaced by Gina Mazany.
A women's flyweight bout between former KSW Women's Flyweight Champion Ariane Lipski and Luana Carolina (originally scheduled for UFC on ESPN: Overeem vs. Harris).

A women's flyweight bout between Melissa Gatto and Mariya Agapova was scheduled for the event. However, Gatto pulled out on June 7 due to visa issues. She was replaced by Hannah Cifers.

A bantamweight bout between Tyson Nam and Ryan Benoit was scheduled for the event. However, Benoit withdrew from the event for an unknown reason and was replaced by promotional newcomer Zarrukh Adashev.

A bantamweight bout between former UFC Flyweight Championship challenger Ray Borg and Merab Dvalishvili was scheduled for the event. However, Borg withdrew from the event for personal reasons and was replaced by promotional newcomer Gustavo Lopez. The bout is now expected to take place at a catchweight of 140 pounds.

Before the weigh-ins, Darrick Minner was pulled from his bout with Jordan Griffin due to unspecified health issues.

At the weigh-ins, Jessica Eye, Karl Roberson and Zarrukh Adashev missed weight for their respective bouts. Eye weighed in at 126.25 pounds, a quarter pound over the non-title flyweight limit. Roberson weighed in at 190.5 pounds, 4.5 pounds over the non-title middleweight limit. Adashev weighed in at 138.5 pounds, 2.5 pounds over the non-title bantamweight limit. All of their bouts will proceed at a catchweight and all fighters will be fined 25%, 30% and 20% of their individual purses.
