The International Bobsled and Skeleton Federation is provisionally suspending four Russian sliders who have been banned from the Olympics for doping violations.
The decision Thursday means Aleksandr Tretiakov, Elena Nikitina, Mariia Orlova and Olga Potylitsyna cannot compete in IBSF competitions. The Russians are likely to appeal.
The decision is in stark contrast to one by the International Ski Federation, which is allowing Russian cross-country skiers who were found guilty of doping at the Sochi Olympics to compete in World Cups this weekend.
Tretiakov and Nikitina were Sochi medalists until the International Olympic Committee stripped those awards Wednesday because of the doping findings. They were planning to compete this weekend in a World Cup at Whistler, British Columbia.
Orlova and Potylitsyna have been racing this season on the lesser-tier Intercontinental Cup Circuit.
