Nigerian sprinter Damola Osayemi has been stripped of her Commonwealth Games 100 metres gold medal after her B sample confirmed a positive test for a banned stimulant.
Osayemi's compatriot, Samuel Okon, who has since tested positive for the same banned stimulant, waived his right to have his B Sample tested.
He has also been disqualified from the Games in Delhi and his 110 metres hurdles result nullified.
