Russian curler Alexander Krushelnitsky has been stripped of his Winter Olympics bronze medal after being found guilty of doping.
The 25-year-old was one of 168 Russians allowed to compete as neutrals at the Games despite the country being banned for previous doping offences.
Krushelnitsky, who won mixed-doubles bronze with wife Anastasia Bryzgalova, tested positive for meldonium.
The Court of Arbitration for Sport said he admitted the anti-doping
violation.
With Krushelnitsky and Bryzgalova's third place annulled, when the bronze medal is officially reallocated it will go to Norway.
The International Olympic Committee banned Russia from this month's Games in Pyeongchang, South Korea over "systemic" doping at Sochi 2014, which Russia hosted.
But athletes who could prove they were clean were allowed to compete as Olympic athletes from Russia (OAR). The team of 168 was the third biggest behind Canada and the United States.
