The International Olympic Committee, IOC, has said, it would take up to a week to decide whether to ban Russia from the Rio Olympics following the World Anti-Doping Agency's report on Russia's state-sponsored doping. The final verdict could come less than 10 days from the Rio opening ceremony on August 5.The IOC executive decided on Tuesday to wait until after a Court of Arbitration in Sport ruling expected today before deciding whether a blanket Olympic ban on Russian competitors should be imposed. The IOC said it needed to study all legal options to determine the legality of a collective ban of all Russian athletes for the Rio Games on the grounds of systematic doping.
