Ukrainian cross country skier Marina Lisogor has tested positive for a banned substance during the Sochi Winter Olympic Games, the Ukrainian Olympic Committee said Saturday.
The 30-year-old skier told a disciplinary hearing that she had unwittingly taken the banned substance, reports Xinhua.
It is the third doping case in Sochi.
Two-time Olympic cross-country skiing champion Evi Sachenbacher-Stehle of Germany tested positive for the banned stimulant methylhexanamine and Italian bobsleder William Frullani was caught for the stimulant dymethylpentylamine.
