Japanese speed skater Kei Saito has become the first athlete to be excluded from the 2018 Winter Olympics for a doping violation.
Saito failed an out-of-competition doping test prior to the Games, the Court of Arbitration for Sport said.
The 21-year-old had not yet competed in the Games but was due to compete in the men’s 5,000m relay on Tuesday.
He tested positive for acetalozamide, a banned diuretic which is considered a masking agent.
The CAS statement said Saito had left the athletes’ Olympic Village voluntarily and would be provisionally suspended from the Olympics and other competitions pending a full investigation.
