However, Brazilian media outlet Tatame spoke with a doctor in charge of the drug tests submitted to the Brazilian MMA Athletic Commission prior to UFC on FX 7, which took place in Sao Paulo (translation via Bloody Elbow).
This is nothing but the same rumor, we don't have the results yet, they have not come out.All fighters who took the test are subject to it, but the agency that works in partnership with us has not yet finalized the results. The two main event fighters always take the test, then two more fighters on the preliminary card and two of the main. There are six athletes tested, but none of them ever had the test results confirmed and finalized yet," Dr. Marcio Tannure said ... The doctor's prediction is that the agency, which has the name withheld by him, won't release the results of drug tests from UFC Sao Paulo until the 19th of February, a month after the event.
