On June 15, the day before a USWNT friendly against World No. 2 Sweden, goalkeeper Hope Solo provided a urine sample that tested positive for Canrenone. Canrenone is not a PED, but rather a diuretic, and is sometimes used to flush the system, so it's a USADA banned substance.
Solo told U.S. Soccer and USADA that the Canrenone was contained in a prescription medication she was taking for legitimate purposes, and they've apparently accepted her excuse. She's only been issued a "public warning," so this won't interfere with her starting for the USWNT at the Olympics.
U.S. Soccer's statement:
"U.S. Soccer received notification from the U.S. Anti-Doping Agency that Hope Solo tested positive for a banned substance from an out-of competition urine sample she provided on June 15. After discussions with Hope, we fully support her clarification that the positive test for Canrenone was due to the use of a prescribed medication from a personal doctor for pre-menstrual purposes and not related to performance enhancement in any way."
Hope Solo's statement:
"I took a medication prescribed by my personal doctor for pre-menstrual purposes that I did not know contained a diuretic. Once informed of this fact, I immediately cooperated with USADA and shared with them everything they needed to properly conclude that I made an honest mistake, and that the medication did not enhance my performance in any way. As someone who believes in clean sport, I am glad to have worked with USADA to resolve this matter and I look forward to representing my country at the 2012 Olympic Games in London."
