Top UFC women’s bantamweight Mayra Bueno Silva is likely to have the biggest win of her UFC career overturned due to the presence of a banned substance in her system that she says stems from the use of ADHD medication.
Bueno Silva, 31, defeated Holly Holm by second-round submission July 15 in the UFC on ESPN 49 main event. On Thursday, Silva has a disciplinary hearing scheduled at the Nevada Athletic Commission’s monthly meeting, which she revealed Monday is due to the failed test.
