GENEVA — As four more Russians were disqualified on Friday for doping at the Sochi Olympics, the president of the International Olympic Committee, 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.

Alexander Zubkov, a two-time bobsled gold medalist, 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 barred for life from the Olympics, along with the speedskater Olga Fatkulina, who won silver in the 500 meters.

Russia originally topped the medals table in Sochi, but the latest cases dropped it to nine gold medals, fewer than Norway and Canada. In total medals, Russia now has 24, behind the United States, Norway and Canada.
