Coates would be "very surprised" if IOC opts to overturn ban on Russia

Coates, seen as a close ally of IOC President Thomas Bach, said he would be "very, very surprised" if the IOC overturned the decision of the International Association of Athletics Federations (IAAF).

"It's an International Federation's right to suspend a National Federation and I don't think we would overturn that at all," he said.

The Australian, who has described the Russian testing system as "rotten to the core", also welcomed similar investigations now taking place within other sports.
