Thirty-two Russian athletes have appealed against their exclusion from the Pyeongchang Games by the International Olympic Committee.
A hearing is likely on Wednesday, two days before the opening ceremony of the Olympics, for athletes including multiple Olympic champion speed skater Viktor Ahn and and biathlon gold medallist Anton Shipulin.
Even if the athletes' appeal is successful, however, it is thought highly unlikely that any of them will compete in South Korea.
It comes after 28 Russian athletes had their Olympic doping bans overturned when their appeals were upheld last week by sport's highest tribunal, The Court of Arbitration for Sport.
The court cleared them to compete but the IOC has refused to invite them.
The IOC has invited 169 carefully-screened Russian athletes who will compete as independents after their country was banned over the doping scandal at the Sochi Winter Games in 2014.
Russia has repeatedly denied state involvement in doping.
