The IAAF said Saturday it has banned the only Russian in Olympic track and field from competition and that she is appealing the ruling.
IAAF spokesman Yannis Nikolaou told The Associated Press that the governing body revoked eligibility for long jumper Darya Klishina based on new information it received last week. Nikolaou would not specify what the new information is or who delivered it.
Klishina, a former European indoor champion, was previously the only one of 68 Russians allowed to compete in the sport amid a massive doping scandal. The IAAF had accepted her application because she is based in the United States. The rest of the Russian team was banned over allegations of a widespread, state-sponsored doping program.
Nikolaou said Klishina has appealed to the Court of Arbitration for Sport and a decision is expected either Sunday or Monday, before the long jump competition begins Tuesday.
Mathieu Reeb, the secretary general of the court, confirmed by e-mail to the AP that an appeal had been filed.
The International Olympic Committee ruled out a blanket ban on Russia last month but imposed new rules which have barred some Russian athletes in various sports because their names were implicated in a report by World Anti-Doping Agency investigator Richard McLaren, who alleged a major doping cover-up.
McLaren said he had received leaked e-mails in which senior Russian Sports Ministry officials discussed whether or not to conceal doping cases related to hundreds of athletes across dozens of Olympic and non-Olympic sports.
Some Russian athletes who featured in that report were able to regain their Olympic spots on appeal to CAS, though others were refused.
