Russia's Olympic Committee has revealed that eight of the country's athletes have registered positive in doping retests from the 2012 London Games.
The brief statement from the ROC did not give names or what disciplines the athletes were in, but said they came from three different sports.
It said further information would not be released until so-called "B samples" were tested that would confirm or contradict the retests.
The International Olympic Committee confirmed on Friday that 23 competitors - including the eight Russians - from the 2012 Olympics failed retests.
The IOC said 265 London samples had been retested with improved techniques, and the 23 failures come from competitors from six countries, competing across five sports.
The athletes have not been named but Sky Sports News HQ understands that no British athletes are involved.
