Teenager sprinter Briana Williams of Jamaica could miss this month’s International Association of Athletics Federations (IAAF) World Championships in Doha after testing positive for the banned diuretic hydrochlorothiazide.
The 17-year-old is the current world under-20 champion in the 100 and 200 metres, with a personal best of 10.94sec in the 100m.
She recorded that time at the Jamaican Championships in June, booking her place at the IAAF World Championships but also reportedly tested positive for the banned substance.
Williams’s representative Emir Crowne has claimed that the substance was contained in an over-the-counter cold-and-flu medication that was given to her by a close relative, but was not listed as an active ingredient, as reported by Jamaican newspaper The Gleaner.
It is also reported that Williams had declared the medication on her doping control form while being tested by Jamaica Anti-Doping Commission officials.
She was made aware of the result on July 25.
