Russian Olympic figure skating champion Kamila Valiyeva has tested positive for the stimulant trimetazidine ahead of the Beijing Winter Games.

This was announced by the International Test Agency ITA, commissioned by the International Olympic Committee (IOC), on Friday morning.

The CAS Court of Justice will decide whether the 15-year-old, who won gold in the team competition with the Russian team on Monday, may take part in the individual competition.

According to the ITA, Valiyeva's positive sample was taken on December 25 at the sidelines of the Russian Figure Skating Championships in St. Petersburg.

The WADA-accredited laboratory in Stockholm announced the positive finding on Tuesday - one day after the Olympic team competition.

The Russian anti-doping agency RUSADA issued a temporary ban, but lifted it again on Wednesday after an objection by Valiyeva.

The IOC appealed against this decision and wants to bring about a clarification before the CAS before the short program in women's singles on February 15th.

Award ceremony cancelled

The fuss began when the Olympic organizers canceled the medal ceremony for the team competition, which was actually planned for Tuesday, without giving any further reasons.

The favored Russian team prevailed ahead of the USA and Japan.

In addition to Valiewa, Mark Kondratiuk (both singles), Anastasia Mishina and Alexander Galljamow (pairs) as well as Wictoria Sinizina and Nikita Kazalapow (ice dance) contributed to the success.

The IOC initially spoke of a "legal procedure" that it could not comment on.

IOC spokesman Mark Adams described media reports about a doping case as "speculation" on Thursday.

The substance trimetazidine is on the World Anti-Doping Agency's banned list.

Russia under surveillance

Russia's athletes are also under particular scrutiny in Beijing.

The country is blocked because of the scandal of state-organized doping and the cover-up of sports fraud, as it was at the Summer Games in Tokyo.

The Russian athletes may only compete as representatives of the Russian Olympic Committee (ROC).

The Russian anthem may not be played and the flag may not be hoisted at award ceremonies.

Super talent Valiyeva is one of the most prominent faces among Russian athletes at the Winter Games.

She only made her adult debut this season and won the European Championship title in January.

In the Olympic team competition, she had won the women's freestyle by a clear margin, making her the top favorite for the individual competition.
