Cris “Cyborg” Justino released a statement in response to her having tested positive for a potential doping violation.

An out of competition drug test taken December 5 by Cyborg was flagged by the United States Anti Doping Agency on Thursday. Cyborg admitted to testing positive for Spironolactone, a diuretic that is at times used as a masking agent to hide the use of other drugs. Spironolactone is on the World Anti Doping Agency list as a drug that is banned at all times. USADA spokesperson, Ryan Madden, confirmed that the Cyborg sample had been found positive. He also elaborated that the standard punishment for an athlete found with Spironolactone in their system is a one year suspension.

“It has been brought to my attention that my recent sample contained a banned substance known as Spironolactone,” wrote Cyborg. “The substance is part of a therapeutic treatment being administered to me by doctor that started the 26th of September and is suppose to last for a period of no less than 90 days, requiring blood exams at the completion.

Cyborg claims that she was prescribed the drug after losing weight to get to 140 pounds for a fight in September.

“In addition to the treatment administered to me by Dr Ulyssea M Da C O Pinto (CRM-PR19062/CRM-RJ 30150-9/CRM SC 2740/ CRM -RO 2630) I was given a medical suspension by her not to enter into competition style training or weight-cutting practices during the period of recovery. It is for those reasons why I declined the UFC fight Feb. 11th  for the first 145 (pound) belt.”
