Another three North Korean footballers at the women's World Cup have tested positive for banned steroids, bringing the total in the squad caught up in the scandal to five. In a bizarre explanation for the failed drugs test, North Korean officials claim the steroids were accidentally taken with traditional Chinese medicines based on musk deer glands. The officials said the remedy was used to treat players who had been struck by lightning at a training camp in June. FIFA's chief medical officer Jiri Dvorak said it is the first time the substance has ever been discovered. This is the biggest case of doping at a major event that FIFA has ever dealt with and the first since Diego Maradona in 1994.
