American judoka Nicholas Delpopolo has been disqualified from the Olympics after failing a drugs test.
Delpopolo lost to Mongolian Nyam-Ochir Sainjargal in the repechage stage of the men's 73kg division a week ago, and was tested after that bout.
"The International Olympic Committee today announced that it has disqualified American judoka Nicholas Delpopolo from the men's 73kg judo event of the Games of the XXX Olympiad in London," read a statement from the IOC.
The 23-year-old tested positive for 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid, linked to cannabis consumption.
