NAC has also overturned Mayra Bueno Silva’s second-round submission win over Holly Holm into a no-contest as the Brazilian tested positive for ritalinic acid in a pre-fight test. The fight served as the main event in a July UFC Fight Night card.
Bueno Silva claimed that the substance was an ADHD medication that she took for years.
“I stopped taking the medication the Monday of fight week. I’ve done this a lot of times, and then this time, I don’t know what happened,” Bueno Silva said in August.
