UFC on ESPN: Holm vs. Bueno Silva—also referred to as UFC Vegas 77, or UFC on ESPN 49—was a mixed martial arts competition organized by the Ultimate Fighting Championship. This event took place on July 15, 2023, at the UFC Apex facility located in Enterprise, Nevada, within the Las Vegas metropolitan region.
Background
The headline fight featured a women's bantamweight clash between former titleholder Holly Holm and challenger Mayra Bueno Silva.
Originally, the main event was expected to be a welterweight contest involving former lightweight champion Rafael dos Anjos versus Vicente Luque. However, this bout was rescheduled to headline UFC on ESPN: Luque vs. dos Anjos for reasons not publicly disclosed.
A flyweight pairing between Jafel Filho and Juancamilo Ronderos had been arranged but was called off when Ronderos withdrew. Subsequently, Filho was matched against newcomer Daniel Bárez at UFC Fight Night: Aspinall vs. Tybura.
Plans for a heavyweight fight between Walt Harris and Josh Parisian were also scrapped following an alleged anti-doping infraction involving Harris, as identified by the United States Anti-Doping Agency (USADA).
Bonus awards
Monetary bonuses of $50,000 were granted to the following fighters:
- Fight of the Night: Jack Della Maddalena vs. Bassil Hafez
- Performance of the Night: Mayra Bueno Silva and Francisco Prado
Aftermath
On August 21, it was revealed that Bueno Silva tested positive for a substance associated with her prescribed ADHD treatment. The Nevada State Athletic Commission conducted a disciplinary hearing on August 24. Subsequently, on October 17, her victory was changed to a no contest status following a suspension lasting four and a half months and a fine due to the detection of ritalinic acid.
