COLORADO SPRINGS - Top US amateur boxer Sadam Ali is awaiting the B sample result from a positive doping test for cathine, a banned stimulant found in some cold medicines.

Ali, a lightweight who won the 2006 US Golden Gloves, tested positive at an exhibition in China in November. The 19-year-old from New York has gone on a voluntary suspension while awaiting the results.

Jim Millman, the CEO of USA Boxing, said Ali and five other American boxers suffered from flu-like symptoms while in China.

Possible penalties, which would be handed down by the International Amateur Boxing Association, could range from a warning to a two-year suspension. To have a chance at making the Olympics, Ali must be eligible for an Olympic qualifier scheduled for March 10-18 in Trinidad and Tobago.

"Sadam Ali is open to any type of investigation pertaining to his past, present or future," Ali's attorney, Salvatore Strazzullo, said on Wednesday. "We're very confident that Sadam Ali will be cleared of any wrongdoing."

Millman said he expects the B test results by the end of the week and is hoping AIBA's decision will follow shortly.

The first doping case of the Athens Olympics in 2004 resulted in the expulsion of Kenyan boxer David Munyasia after his positive test for cathine in an out-of-competition test.
