The sports chief of the Russian Olympic team in Rio says Russian athletes who arrived in Rio early are under scrutiny of WADA doping agents.
Igor Kazikov told state-owned television channel on Friday that every member of the team who had arrived by Thursday has already been tested for doping at least once.
"I can see that every morning doping agents come and take their samples," Kazikov said. He added, however, that he was not sure how that compares to how often athletes from other countries get tested.
