Cynthia Calvillo vs. Katlyn Chookagian in the works for UFC 255 in Las Vegas

A top-tier women’s flyweight matchup is in the works for UFC 255.

The promotion is targeting contenders Cynthia Calvillo and Katlyn Chookagian to fight one another at the Nov. 21 pay-per-view event at the UFC Apex in Las Vegas.

A person with knowledge of the targeted booking confirmed the matchup to MMA Junkie on Monday after an initial report by ESPN.

The fight takes place on the same card the division’s titleholder Valentina Shevchenko defends her belt against Jennifer Maia.

Calvillo (9-1-1 MMA, 6-1-1 UFC) was supposed to compete on Oct. 24 at UFC 254 against Lauren Murphy. However, Calvillo withdrew from the fight days prior due to a positive COVID-19 test.

Since losing to Carla Esparza in December 2017, Calvillo has gone 3-0-1 with wins over Poliana Botelho, Cortney Casey, and most recently, Jessica Eye.

Chookagian (14-4 MMA, 7-4 UFC), a one-time UFC women’s flyweight title contender, has lost two of her most recent three fights. She was knocked out by titleholder Valentina Shevchenko at UFC 247 in February and rebounded with a unanimous decision win over Antonina Shevchenko in May.

In her most recent outing, which took place in October, Chookagian was finished with body punches by former UFC women’s strawweight champion Jessica Andrade.

• Champ Deiveson Figueiredo vs. Alex Perez – for flyweight title
