SOCHI, Russia - The IOC says a Latvian hockey player has been expelled from the Sochi Olympics after failing a doping test.
The International Olympic Committee says Vitalijs Pavlovs tested positive for the stimulant methylhexaneamine after Latvia's loss to Canada in the quarterfinals.
He is the fourth athlete to fail a drug test at the games.
Earlier Saturday, the Ukrainian Olympic Committee said cross-country skier Marina Lisogor tested positive for the stimulant trimetazidine.
The latest positive tests follow those of German biathlete Evi Sachenbacher-Stehle and Italian bobsledder William Frullani.
