Hope Solo has received an official warning from the USDA regarding the results of a drug test, although she will still be allowed to compete on the Olympic team.

Solo tested positive for a substance called Canrenone, a diuretic which was in prescribed medication and which Solo took unknowingly. However, because she immediately began working with the USDA after the test, she has been given a warning only and still intends to play for the U.S. national team, where she is a goalkeeper.

Solo issued a statement about the test and the reprimand:

“I took a medication prescribed by my personal doctor for pre-menstrual purposes that I did not know contained a diuretic,” Solo said in a statement. “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,” she said.

Solo has been the goal keeper for the U.S. team for six years and is considered one of the best in the world.
