The 15-year-old star of Russia’s figure skating team who powered it to a win in the team figure skating competition tested positive for a banned substance at a national competition leading up to the Games, throwing the team’s gold medal into question.
The skater, Kamila Valieva, was found to have used trimetazidine, a heart medication not normally allowed in competition, according to a statement Friday from the International Testing Agency.
It was unclear if Russia’s team, which won the event Monday, beating the United States in second and Japan third, would be awarded the gold medal.
