Valieva's entourage under investigation by World Anti-Doping Agency

Kamila Valieva, 15, of the Russian Olympic Committee, reacts after the women's team free skate program during the figure skating competition at the 2022 Winter Olympics, Monday, Feb. 7, 2022, in Beijing. Valieva is at the center of the biggest doping story of the Games.

The world's top anti-doping authority will investigate the entourage of 15-year-old Russian figure skater Kamila Valieva who tested positive for a banned drug, plunging her into a doping scandal at the Beijing Winter Olympics.

Valieva, whose Olympic future will be decided after a Court of Arbitration for Sport (CAS) hearing at 8:30 p.m. (local time), effortlessly completed a clean run through of her short program in practice Sunday.

Watching her from the sidelines were her three coaches, Eteri Tutberidze, Sergei Dudakov and Daniil Gleikhengauz, as well as the team doctor Filipp Shvetsky and a physiotherapist.

The World Anti-Doping Agency (WADA) said in a statement to Reuters, Sunday, that it would ask its independent Intelligence and Investigations Department to probe the coaches, doctors and other adults surrounding the athlete.

Earlier, the International Olympic Committee (IOC) said it had formally asked WADA to launch an investigation.

WADA also said that the Russian Anti-Doping Agency (RUSADA) has indicated it has already started investigating the entourage because Valieva is a minor.

Valieva tested positive for a banned heart drug at her national championships last December, but it took more than six weeks for her to be notified, allowing her to compete in Beijing.

Her future at the Games, and a gold for the Russian Olympic Committee in the team event that she dominated Monday, now hang in the balance amid a global outcry over Moscow's doping history.

Tutberidze, the most sought after figure skating coach in Russia, has not responded to Reuters emails.

On Saturday, she said she was certain Valieva was "clean and innocent" in an interview with Russian state television.

At 15, Valieva is one of the youngest athletes to have a positive test revealed at the Olympics, prompting outrage and questions about the role of the adults around her and the continuing scourge of Russian doping in international sport.

The IOC set up the entourage commission in 2010 as positive drug cases of athletes mounted in the 2000s, especially with the re-testing of samples of past Olympics.

Russia's state-backed doping scandal after the 2014 Sochi Olympics made more apparent that athletes often did not act alone but were supported by a wider network, including medics, coaches, agents, and family and friends.

The commission can sanction individuals for a number of violations that include doping, unsportsmanlike conduct and harassment. Sanctions can range from reprimands to permanent exclusion from the Olympics.

On Sunday, however, it will be Valieva's future at the Games that is debated. A panel of three judges for CAS will hear arguments from the IOC, WADA and International Skating Union to reinstate a ban lifted by the Russian Anti-Doping Authority, Feb. 9.

At stake is Valieva's entry in the women's single event Tuesday. CAS has said it will notify all parties Monday.

The fate of the gold medal that has still not been awarded for the Feb. 7 women's team event is likely to take longer to clear up. (Reuters)
