Rony Jason denies diuretic use, but second drug test result comes back positive

Rony Jason tested positive following his UFC Fight Night 67 win over Damon Jackson, and threatened to sue the Brazilian MMA Athletic Commission (CABMMA) if his B sample came back negative. However, the Brazilian featherweight’s B sample also tested positive for diuretic hydrochlorothiazide.

CABMMA announced on Tuesday that Jason’s urine sample was analyzed by WADA-accredited UCLA Olympic Analytical Laboratory, and came back positive. As a result, Jason is suspended nine months, and his first-round submission victory is overturned to a no-contest.
