Russian figure skater Kamila Valieva's fate to be decided by Court of Arbitration for Sport

Russian figure skater Kamila Valieva's right to compete in the women's event at the Beijing Olympics will be decided at an urgent hearing at the Court of Arbitration for Sport.

Both the World Anti-Doping Agency and the International Testing Agency — on behalf of the IOC — said Friday they would fight the decision by Russia's anti-doping agency to allow the 15-year-old Valieva to skate. The Russian agency provisionally banned Valieva Tuesday because she failed a doping test in December. After an appeal, the agency lifted the ban Wednesday.

Valieva is the heavy favourite in her event, which begins Tuesday. She set world record scores this season and landed the first quad jump by a woman at an Olympics as the Russian Olympic Committee won the team event. The ROC said it will fight to keep that gold medal, and Valieva has passionate support from the Kremlin.

The ITA confirmed reports that Valieva tested positive for the banned substance trimetazidine at the Russian national championships in St. Petersburg six weeks ago.

An AP request for comment by the Swedish lab on the delay was not immediately answered.

"We have the same questions as everyone else about the team figure skating case. It's important that a fair process unfolds and the integrity of sport is protected. Our hope is that this is resolved quickly and the medallists get the medal moment they've earned here in Beijing," said Eric Myles, Chief Sport Officer for the Canadian Olympic Committee.

Valieva was hit with an immediate interim ban from the Beijing Olympics by the Russian anti-doping agency known as RUSADA, which oversaw testing at the national championships. On Wednesday, a RUSADA disciplinary panel upheld her appeal and overturned the skater's interim ban.
