Rower Loses One Medal, Keeps One

Rower Silken Laumann of Canada was stripped of one Pan American Games gold medal Thursday and allowed to keep another after testing positive for a stimulant that was in a cold medicine.

Mario Vasquez Rana, president of the Pan American Sports Organization, said the executive committee voted to withdraw the gold medal for the quadruple sculls. The gold will go to Cuba, the silver to the United States.

Laumann will be allowed to keep her single sculls gold because she did not test positive for ephedrine after Saturday’s race.

Through Thursday, the United States had set a games record for silver medals with 126. It has 143 gold and 89 bronze for 358, 11 short of the record set in Indianapolis in 1987.
