Budgett stressed that Olympic athletes from Russia were the focus of the IOC before and during the Games, and that the IOC could be confident that those who have come to South Korea's Pyeongchang are "clean."
The IOC invited 169 Russian athletes to compete in the games. Earlier, CAS fully overturned the IOC ban for 28 Russian athletes, and 11 others got their appeals partially upheld but several Russian athletes have not received any invitation anyway.
Richard Budgett also said that about 2,500 doping tests will be taken at the Winter Olympic Games in South Korean Pyeongchang, including around 1,000 in-competition.
"The test distribution plan… is for around 2,500 tests, with over 1,400 of these being out-of-competition and just over 1,000 in-competition," Budgett said at a press conference, streamed by the IOC.Budgett explained that this was one of the most charged periods of testing in the year.
