The International Skating Union (ISU) said on Friday it will ask the Court of Arbitration for Sport (CAS) to reinstate the decision to suspend Russian figure skater Kamila Valieva from the Beijing Olympics over a positive doping test.
Valieva, 15, won a gold medal with the Russian Olympic Committee (ROC) in the figure skating team event in Beijing, but the award ceremony has been postponed indefinitely.
The International Testing Agency (ITA) revealed on Friday that the skater tested positive in December for the heart medicine trimetazidine.
The sample was taken during the Russian Figure Skating Championships in St. Petersburg.
It was tested at a laboratory in Stockholm accredited by the World Anti-Doping Agency (WADA), which reported the positive result on February 8, a day after the team event in Beijing concluded, the ITA said.
