Russia confirms it will appeal 4-year Olympic ban

Russia confirmed Friday that it will appeal its four-year Olympic ban for manipulating doping data.

The Russian anti-doping agency, known as RUSADA, sent a formal letter disagreeing with the sanctions imposed earlier this month by the World Anti-Doping Agency. The case is now heading to the Court of Arbitration for Sport (CAS).

Next year’s Olympics in Tokyo will be the third consecutive edition of the games preceded by a legal battle over Russian doping issues.
