GENEVA — As four more Russians were disqualified Friday for doping at the Sochi Olympics, the International Olympic Committee President Thomas Bach told critics not to put pressure on his executive board before a key decision next month on Russia’s participation at the Pyeongchang Games.
The two-time bobsled gold medalist Alexander Zubkov was removed from the 2014 records in the latest round of verdicts from an I.O.C. panel prosecuting individuals caught in a program to cover up doping and tamper with tainted samples.
Zubkov, who now serves as president of the Russian bobsled federation, was disqualified and banned for life from the Olympics along with the speedskater Olga Fatkulina, who won silver in the 500 meters.
