Lausanne, Switzerland: Sochi luge silver medallists Albert Demchenko and Tatyana Ivanova were among a group of 11 Russians disqualified for doping and handed lifetime bans by the International Olympic Committee on Friday.
The announcement comes following hearings by an IOC commission into allegations of state-sponsored doping by hosts Russia at the 2014 Winter Games.
Demchenko and Ivanova were punished along with two speed skaters, three cross-country skiers, two bobsledders and two ice hockey players.
These latest IOC sanctions bring to 43 the number of Russians caught out by the Oswald Commission into doping at Sochi with three cases pending.
"As some investigations are still ongoing (notably the forensic analysis of the bottles), it cannot be excluded that there might be new elements that would justify opening further new cases and holding more hearings," the IOC said in a statement.
The raft of punishments has seen Russia lose top spot in the Sochi medals table having been stripped of 13 of their original 33 medals for cheating, slipping down to fourth overall behind Norway, Canada and the United States.
Russia has been banned from taking part at next year's Winter Olympics in Pyeongchang, South Korea due to this widespread doping.
However, athletes who prove themselves to be clean have been told by the IOC they can compete under strict conditions, and under a neutral flag.
The Russian doping fiasco came to light after the damning World Anti-Doping Agency-sponsored McLaren report deemed the country to have set up an elaborate doping programme involving the manipulation of drug test samples.
Mounting evidence has indicated that the scheme involved senior government officials, including from the Russian sports ministry, with help from secret state agents.
