Following the country's well-documented doping offences, the IOC ruled this month that only carefully vetted Russians could compete in Pyeongchang as neutral athletes, in uniforms that say "Olympic Athlete from Russia" and/or "OAR".
Even though Russian Federation is banned from the 2018 Winter Olympics as a result of an alleged state-backed doping program, which helped hide test results from hundreds of athletes using performance-enhancing drugs, the International Olympic Committee said that some of the country's athletes may receive "special dispensation" to compete.
Silver medal-winning lugers Tatyana Ivanova and Albert Demchenko are among those to have been disqualified.
There will also be no Russian anthems or flags in the opening or medal ceremonies.
The results of the athletes will be annuled, and those who won medals will have them stripped. However, athletes who prove themselves to be clean have been told by the International Olympic Committee they can compete under strict conditions, and under a neutral flag.
Russian Federation has been banned from taking part at next year's Winter Olympics in Pyeongchang, South Korea due to this widespread doping.
The IOC announced the first Russian bans, based on the findings of the 2016 McLaren report, on 1 November.
Legkov, along with more than 20 other Russian athletes, has vowed to fight the ban at the Court of Arbitration for Sport (CAS).
The International Olympic Committee has revealed 13 guidelines for Russia's neutral uniforms at the Winter Games in February. A final decision on participation will be made in January, it said.
