Russia confirms it will appeal 4-year Olympic ban

 Russia has confirmed 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 Friday 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.

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

RUSADA's own CEO, Yuri Ganus, attached his own note of protest to Friday's letter. Ganus is critical of Russian officials and had disagreed with the decision to appeal. He was overruled by his agency's founders, which include some of Russia's most influential sports leaders.

The WADA sanctions ban the use of the Russian team name, flag or anthem at a range of major sports competitions over the next four years, including next year's Olympics and the 2022 soccer World Cup.

However, Russian athletes will be allowed to compete as neutrals if they pass a vetting process which examines their history of drug testing, and possible involvement in cover-ups at the lab.
