The Court of Arbitration for Sport announced on Thursday that it has rejected the claims and appeal of the Russian Olympic Committee and 68 athletes who had challenged a ban from the track federation that would keep the country from competing in Rio.
CAS announced the decision in a one-sentence release on its website.
The athletes and ROC had challenged a ban by the International Association of Athletics Federations in June that will keep the team from going to the Summer Olympics.
The CAS decision comes amid calls from athletes and anti-doping officials for the IOC to ban Russia from the Rio Olympics following the release of another WADA report this week that revealed even more widespread doping issues than previously known.
