Athletes from Russia and Belarus may not be allowed to compete at the Paris 2024 Games, senior International Olympic Committee (IOC) member Craig Reedie said.
"A decision is going to have to be taken on what happens to each of these two countries, and my guess is that the general feeling would be that they should not qualify," former IOC vice-president Reedie told British media.
Reedie, former president of the World Anti-Doping Agency (WADA), said it would be unrealistic to allow athletes to enter qualifying competitions once they have begun.
"It's quite difficult halfway through to say, 'All of you who have now qualified we've changed the rules'," Reedie said. "So there's a real issue for the federations, who have a clear instruction which they've agreed to that they won't invite Russians and Belarusians to take part in events.
"On the face of it, it's unlikely that anybody would qualify other than those three sports which don't do it that way. And will they be able to qualify (from those three sports)? I'm not sure," he added.
