UFC on ESPN: Cannonier vs. Imavov

UFC on ESPN: Cannonier vs. Imavov (also known as UFC on ESPN 57) was a mixed martial arts event produced by the Ultimate Fighting Championship that took place on June 8, 2024, at the KFC Yum! Center in Louisville, Kentucky, United States.

Background
The event marked the promotion's second visit to Louisville and first since UFC Live: Sanchez vs. Kampmann in March 2011.

A middleweight bout between former UFC Middleweight Championship challenger Jared Cannonier and Nassourdine Imavov headlined the event.

A bantamweight bout between Raul Rosas Jr. and The Return of The Ultimate Fighter: Team Volkanovski vs. Team Ortega bantamweight winner Ricky Turcios took place at the event. They were originally scheduled to meet at UFC Fight Night: Moreno vs. Royval 2 on February 24, but Rosas Jr. was forced to withdraw just before the bout was expected to begin due to an illness. As a result, the pairing was initially pushed back one week to UFC Fight Night: Rozenstruik vs. Gaziev before it was ultimately cancelled by the promotion.

A middleweight bout between Roman Dolidze and Michel Pereira was briely announced as part of the event. However, Pereira claimed he never signed any contracts for the fight and the bout fell through.

At the weigh-ins, Eduarda Moura weighed in at 116.5 pounds, half a pound over the women's strawweight non-title fight limit. The bout proceeded at catchweight and Moura was fined 20 percent of her purse which went to her opponent Denise Gomes.
