Mayra Bueno Silva Reveals She Failed Pre-Fight USADA Test Leading Up To Holly Holm Win

Originally posted on MMA News | By Curtis Calhoun | Last updated 8/21/23

UFC bantamweight contender Mayra Bueno Silva tested positive for an undisclosed banned substance ahead of her latest win.

Bueno Silva defeated former UFC champion Holly Holm by second-round submission for her fourth consecutive victory. She is knocking on the door of a potential bantamweight title shot; a belt now vacant after Amanda Nunes' retirement.

Bueno Silva is on a roll in the UFC's bantamweight division and has boosted her name recognition following her win over Holm. But, she's suffered a setback to her title contention.

Bueno Silva announced in a recent social media post that she tested positive for a USADA-banned substance leading up to the fight with Holm. She faces a potential suspension, pending appeal and further investigation into the infraction.

"To all my fans, it is with deep regret I have to announce I failed a drug test that I took the week of my fight against Holly Holm," Bueno Silva began. "I want to begin by saying I have never in my life taken a substance to enhance my ability in or outside the cage. I have tested positive for a substance that is consistent with the prescription medication I take for my ADHD...I am fully cooperating with USADA, the Nevada State Athletic Commission and the UFC to make sure that all information is available and I fully acknowledge the presence of the substance in my system...I look forward to fighting again for the best organization in the world. I am the next champion and I am ready to fight!"

Bueno Silva bounced back from a loss to Manon Fiorot with recent finishes of Stephanie Egger and Lina Länsberg. She earned a shot in the UFC following a win on Dana White's Contender Series: Brazil in 2018.

USADA suspensions are typically 6-12 months in length, although it sounds like Bueno Silva's infraction was based on a prescription and not intentional.
