World-Anti-Doping Agency (WADA) investigator Richard McLaren has told German TV network ARD that 155 samples related to Russian footballers have been reported to FIFA, saying he believed those samples were part of a doping cover-up.
McLaren said he believed this could be part of a cover-up separate to that revealed in the report that led to the banning of Russian athletes from the Olympic Games in Brazil.
"There are 155 samples that were seized by WADA and are awaiting analysis. We have reported those to FIFA," McLaren said.
He added that he believed the samples had either been opened and manipulated or would show the existence of doping substances.
