The International Olympic Committee said Friday that 28 Russian athletes could face disciplinary proceedings after urine samples from the 2014 Sochi winter Olympics were allegedly manipulated.
The IOC said that for the 28 athletes there was "evidence of manipulation of one or more of their urine samples." The IOC said that would be re-analyzing the urine samples of all Russian athletes from the Sochi games in 2014 as athletes who participated in the 2012 London Olympic Games.
The re-analyzing will go beyond the damming McLaren report from the World Anti-Doping Agency which found that over 1,000 Russian athletes across 30 sports were involved in a systematic scheme to hide positive drug tests over five years.
The committee stressed that while the 28 samples are not necessarily regarded as positive test results, some athletes may face disciplinary sanctions. The McLaren report claimed that there was evidence of 12 urine samples of Russian Sochi medalist were manipulated and that four gold medalists from the 2014 games had samples with suspect salt readings.
Amid the fallout from the scandal, a number of athletes have already been suspended and Russia banned from hosting a number of sporting competitions.
The International Ski Federation announced that it had suspended six Russian cross-country skiers who are under investigation. Russia will no longer host the 2017 Bobsleigh World Championships and has pulled out of a number of cross-country events.
Russian President Putin has been critical of the report and downplayed its accusations of a state-sponsored system of doping, while others have argued the report contains a number of inaccuracies.
Speaking Friday Putin said that while there were some problems in Russian sport, it should not be politicized.
