Sports | Jessica Hardy US Swimmer 'Tests Positive for Banned Substance' Source: Jessica Hardy has failed pre-Olympics doping test By Rob Quinn Posted Jul 24, 2008 5:10 AM CDT Copied In this June 30, 2008, file photo, Jessica Hardy swims in women's 100-meter breaststroke semifinals at the U.S. Olympic swimming trials in Omaha, Neb. (AP Photo/Nati Harnik, File) American swimmer Jessica Hardy's Olympics may already be over. The 50-meter breaststroke world record holder has tested positive for a banned stimulant, insiders told the AP. Hardy has the right to pursue appeals, but if they fail she could face a 2-year ban and Team USA will suffer a major blow to its Olympic hopes. Hardy had been expected to challenge for a medal in the 100-meter breaststroke and play a key role in the 400-meter free relay. The 21-year-old's agent said the swimmer had denied doping and he was "very, very concerned" about conflicting test results. He added "She's the one person I would never believe would do anything—anything—to cheat. Ever." Read These Next Iran's supreme leader makes first public comments since ceasefire.
