DES MOINES: U.S. wrestler Stephany Lee has been suspended for a year and must give her up spot on the Olympic team after testing positive for marijuana.

The U.S. Anti-Doping Agency on Thursday says Lee tested positive for tetrahydrocannabinol acid, a marijuana metabolite, at the Olympic Team Trials in Iowa City on April 21.

Lee, who also tested positive for marijuana in 2009, has accepted the sanctions. She must forfeit any medals, points or prizes dating back to her positive test.

Ali Bernard, who lost to Lee in a best-of-three championship series at the Olympic Trials at 72 kilograms, has been declared the trials champion and has been nominated to represent the United States in London.
