Reports on the Internet state that US swimmer Jessica Hardy, Olympic qualifier in the 50 freestyle and the 100 breaststroke, had a positive result on both an A and B doping test at the US Olympic Trials. She had a negative on one day, a positive a few days later, then another negative a few days after that.

If true, she is off the team (that is obvious) but no one can be added to the US roster, so others on the roster would/could fill her events. The specific results were positive for the stimulant clenbuterol.
