US judoka expelled from London Olympics for doping

American judo fighter Nick Delpopolo was expelled from the London Olympics on Monday after testing positive for cannabis.

Delpopolo is the first of the 10,500 London Games athletes to fail an in-competition doping test.

The International Olympic Committee said it disqualified Delpopolo from the men's 73-kilogram class, where he placed seventh.

The IOC says Delpopolo tested positive for metabolites of cannabis after competing on July 30.

Delpopolo "shall have his Olympic identity and accreditation card canceled and withdrawn immediately," the IOC said.

The IOC said it would ask the International Judo Federation to alter the standings in Delpopolo's event.

Delpopolo faces further sanctions as the IOC requested that judo's governing body "consider any further action within its own competence."

The 23-year-old Delpopolo comments on his official games biography that he found training for London to be intense and he would like to return to study.

"I would also like to try and get a job wherever; it wouldn't matter to me," he is quoted as saying on the official website. "These two things would be a good change of pace from the 'always train' life I live now.

"Don't get me wrong, I would still practice, train and compete judo but not as intense or as much as I am now. But in 2014 I would start preparing for the 2016 Games again."

Delpopolo was born Petra Perovic in the republic of Montenegro in the former Yugoslavia, the biography said.

He was adopted by an American family who named him Nick and he grew up in New Jersey.

His case is the fifth positive test for a banned substance reported by the IOC within the official London Olympics testing period.
