The U.S.  Anti-Doping Agency (USADA) has suspended former UFC middleweight champion Anderson Silva for a period of one year for his second positive drug test.

According to MMA Junkie, the suspension is retroactive  to Nov. 10, 2017, which means he’ll be able to return to competition on Nov. 10 of this year. The USADA reportedly traced  his second positive drug test to a compounding pharmacy known for producing tainted supplements.

Silva (34-8 MMA, 17-4 UFC) called the settlement vindication.

“The past nine months have been extremely difficult,” he said. “I felt like my career and everything I had worked so hard for was dying and my future was hanging in the balance. I knew in my heart that I had done nothing wrong and fully cooperated with USADA during their inquiry to prove it.”

The 43-year-old was flagged for three separate methyltestosterone metabolites and the diuretic hydrochlorothiazide following an out-of-competition urine test conducted Oct. 26. The USADA reportedly  examined a “compounded dietary supplement product” he was using at the time of his positive test, and a World Anti-Doping Agency-accredited laboratory verified the banned substances found in the product. The compounding pharmacy that prepared Silva’s supplement was found to “contain similarly contaminated prohibited substances, including multiple anabolic agents and diuretics.”

The suspension marks Silva’s second yearlong ban in the past three. In 2015, he was suspended for one year after failing two drug tests stemming from an overturned win against Nick Diaz at UFC 183. He claimed the positive test was the result of a sexual enhancer that a friend from Thailand had given him.
