Pyeongchang, South Korea: A fresh Russian doping case overshadowed the team's first gold medal at the Pyeongchang Winter Games on Friday and could lower the country's chances of an early return to the Olympic fold.
Russia's bobsleigh federation said female pilot Nadezhda Sergeyeva had tested positive for a "heart medicine" which is on the World Anti-Doping Agency's list of banned substances.
Russia's second doping case in Pyeongchang, after curler Alexander Krushelnitsky was stripped of his mixed doubles bronze medal, comes as Olympic officials consider whether to lift Russia's suspension following a major drugs scandal.
"A doping test by the pilot of the Russian team Nadezhda Sergeyeva on 18 February gave a positive result for a heart medicine that is on the banned list," a Russian bobsleigh federation statement said.
Sergeyeva placed 14th in the women's bobsleigh on Wednesday, partnered by brakewoman Anastasia Kocherzhova.
She is among 168 Russians who passed extended vetting to compete as neutrals in Pyeongchang, after Russia's national Olympic committee was suspended over systemic doping culminating at the Sochi 2014 Winter Games.
Despite the extra screening by anti-doping experts, Russians have accounted for half of the drugs cases in Pyeongchang. Japanese short-track speed skater Kei Saito and Slovenian ice hockey player Ziga Jeglic are the other two athletes to fail tests.
Box of tissues
Sergeyeva's case came to light shortly after 15-year-old Alina Zagitova led a Russian one-two in the women's figure skating, securing the first gold for the neutrally flagged Olympic athletes from Russia team.
Zagitova scored exactly the same as Evgenia Medvedeva in the free skate, but edged the 18-year-old two-time world champion by 1.31 points thanks to her sublime, world-record short programme on Thursday.
"I can't believe I'm the champion," said Zagitova, who is still in her debut season on the senior circuit. "It'll take some time to sink in."
The result appeared devastating for Medvedeva, who was so overcome she was unable to finish a TV interview. An Olympic official followed her round with a box of tissues.
Sergeyeva's positive test also came on a day when the Russians reached the men's ice hockey final by beating the Czech Republic 3-0 -- with goaltender Vasili Koshechkin making a game-winning 31 saves.
It gives them a fabulous chance of winning their first Olympic title since 1992 in Sunday's final, when they will face Germany who stunned Canada, the two-time defending champions, 4-3.
Also on Friday, Kelsey Serwa beat Canada team-mate Brittany Phelan to win the women's ski cross title, which has been in Canadian hands since the sport's Olympic debut in 2010.
Sweden won the men's 4 x 7.5km biathlon relay, denying French army officer Martin Fourcade his fourth gold medal of the Games. Norway and Germany were second and third, while France placed fifth.
Elsewhere, Dutch speed skater Kjeld Nuis won his second gold medal of Pyeongchang in the men's 1,000m speed skating.
And South Korea's women's curling team, a surprise package and smash hit with domestic fans, edged arch-rivals Japan 8-7 to set up a final against Sweden.
Olympic officials will decide over the weekend whether to ease Russia's suspension and allow their athletes to wave the national flag at Sunday's closing ceremony.
Officials have raised the prospect this week of "partially" lifting Russia's suspension, which was imposed in December after revelations of a highly orchestrated doping plot.
