Brazilian UFC fighter Mayra Bueno Silva has tested positive for a banned drug, and now the result of her fight against American Holly Holm will likely be canceled.
It is with deep regret that I have to announce I failed a drug test that I took the week of my fight against Holly Holm. 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 have been dealing with this disorder my entire life and it affects me in a multitude of ways.
