(CNN) -- Commonwealth Games women's 100m winner Oludamola Osayomi has failed a doping test, organizers said on Monday.
The Nigerian sprinter tested positive for a banned stimulant, Commonwealth Games Federation president Mike Fennell told reporters in New Delhi. Tests of Osayomi's B sample are being conducted and a hearing will be held later Monday.
The result is the first positive result from 700 completed tests at the games so far, Fennell said.
Osayomi, 24, was handed the gold medal in Thursday's race after Australian Sally Pearson was disqualified for a false start.
If Osayomi is disqualified Natasha Mayers of St Vincent and the Grenadines would claim gold, England's Kathryn Endacott would gain silver and Bertille Atangana of Cameroon would collect the bronze medal.
Meanwhile, hosts India surged into second place in the medals table on Sunday with a mini-gold rush which at last drew large crowds to the crisis-ridden games.
The Major Dhyan Chand stadium was packed to its 19,000 capacity to see India's field hockey team thrash neighbors Pakistan 7-3, with Sandeep Singh starring, to reach the semifinals of the competition.
