The Court of Arbitration for Sport on Thursday dismissed a Russian appeal against a ban imposed by athletics governing body the IAAF over state-run doping, barring the country's track and field team from the Rio Games. 

"The CAS Panel has confirmed the validity of the IAAF's decision to apply Rules...which state that athletes whose national federation is suspended by the IAAF are ineligible for competitions held under the IAAF Rules," a statement from the Lausanne based court said. 

The International Olympic Committee had said the CAS ruling will help shape its decision on whether to ban Russia entirely from the Rio Games.
