American judo fighter Nick Delpopolo won’t be headed home from London with a gold medal, but he will go down in history as the first athlete expelled from the XXX Olympiad for failing an in-competition doping test. You lose some, you lose some.

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

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

He apologized to the United States team in a statement acknowledging he was "embarrassed by this mistake."

"My positive test was caused by my inadvertent consumption of food that I did not realize had been baked with marijuana, before I left for the Olympic Games," Delpopolo said in a statement released by the U.S. Olympic Committee.

Classic excuse right there. If he’s telling the truth, that’s a pretty bad beat.

Speaking of bad beats, good luck to the person who served up the cannabis-flavored dish to A PROFESSIONAL FIGHTER before he went off to tangle with the world’s best.
