Jamaican World Under-20 double sprint gold medalist and national junior record holder Briana Williams will face an anti-doping disciplinary hearing in the coming weeks after testing positive for the banned diuretic, Hydrochlorothiazide (HCTZ).
Williams's "B" sample has confirmed the "A" sample as being positive for the masking agent.
Both those samples were tested at the WADA accredited lab in Montreal.
Hydrochlorothiazide (HCTZ) is a diuretic used by some athletes to lose weight or mask the use of anabolic steroids.
Pending the disciplinary hearing, Williams who clocked a yet to be ratified national junior record of 10.94 seconds to place third in the 100m final on June 21 at the national senior trials, could now miss the IAAF World Athletics Championships in Doha, Qatar from September 27 to October 7.
