SOCHI, Russia (AP) The Ukrainian Olympic Committee says cross-country skier Marina Lisogor has failed a doping test, the third positive result of the Sochi Games.
Lisogor tested positive for trimetazidine, which is classified as a ''specified stimulant'' on the World Anti-Doping Agency's prohibited list. Specified substances are considered more susceptible to inadvertent use and can carry reduced penalties.
Lisogor competed in two cross-country events at the Sochi Games, finishing far out of the medals.
According to the Ukrainian Olympic Committee on Saturday, Lisogor says she did not knowingly take a banned substance.
Lisogor's failed drug test follows those of German biathlete Evi Sachenbacher-Stehle and Italian bobsledder William Frullani.
