UFC on ESPN: Namajunas vs. Cortez

UFC on ESPN: Namajunas vs. Cortez (also known as UFC on ESPN 59) was a mixed martial arts event produced by the Ultimate Fighting Championship that took place on July 13, 2024, at the Ball Arena in Denver, Colorado, United States.

Background
The event marked the promotion's seventh visit to Denver and first since UFC Fight Night: The Korean Zombie vs. Rodríguez in November 2018.

A women's flyweight bout between former two-time UFC Women's Strawweight Champion Rose Namajunas and Maycee Barber was expected to headline the event. However, Barber withdrew from the bout, due to what was later revealed to be ongoing health problems, and was replaced by Tracy Cortez, who was scheduled to face Miranda Maverick one week later at UFC on ESPN: Lemos vs. Jandiroba.

Chris Duncan was scheduled to face Nazim Sadykhov in a lightweight bout. However, Duncan was replaced by Marquel Mederos due to undisclosed reasons. A week later, Mederos pulled out and the bout was scrapped.

A lightweight bout between Drew Dober and Mike Davis was expected to take place at this event. However, Davis was forced to withdraw due to a torn bicep. He was replaced by Jean Silva, who just fought two weeks earlier at UFC 303.

A welterweight bout between Mike Malott and Gilbert Urbina was scheduled to take place at this event. However, two weeks before the event, as a result of Urbina withdrawing due to undisclosed reasons, Malott decided not to fight another opponent at this event due to an injury sustained during training, so the bout was scrapped.

Viviane Araújo and Jasmine Jasudavicius were expected to meet in a women's flyweight bout. However on July 5, Araújo pulled out for unknown reasons and was replaced by promotional newcomer Fatima Kline.
