It could have been worse. Hope Solo, one of the stars of the U.S. Olympic soccer team, was given a warning by the U.S. Anti-Doping Agency after she tested positive for canrenone, a banned diuretic. Solo had taken a prescription drug to help with her menstrual cycle and said she was unaware that the medication included an illicit substance. Since the medication was prescribed by a doctor, Solo was given a warning instead of a suspension. She is still expected to compete for the U.S. in London.
