This is still unclear. Bach says IAAF will make individual decisions concerning each athlete. In the event they are able to present convincing proof of their innocence, they will be allowed to participate. But each athlete will have to go through an additional, intensified doping test.

On the contrary, IAAF has said that it would not review each Russian athlete's individual complaint. It says the only way they can participate in Rio is if the athletes file a lawsuit with the Court of Arbitration for Sport in Lausanne.
