Russian athlete Nadezhda Sergeeva has tested positive for a banned substance at the Winter Olympics just days after ironically wearing an 'I don't do doping' jumper in a promotional video.
Sergeeva became the second Russian to test positive for a banned substance at Pyeongchang 2018, heaping even more embarrassment on the International Olympic Committee.
Sergeeva, who finished 12th in the two-woman bob with Anastasia Kocherzhova, failed a test for the stimulant trimetazidine.
It comes less than 24 hours after Aleksandr Krushelnitckii was stripped of his mixed doubles curling bronze medal and a day before the IOC discuss whether the Russian's Olympic ban can be lifted in time for Sunday's closing ceremony.
