DuPree receives warning for using asthma medication

EUGENE, Ore. -- Heptathlete Ryanne DuPree, who is aiming for a spot on the Olympic team this week at the U.S. track and field trials, received a warning Wednesday for using asthma medication without getting the proper clearance from anti-doping authorities.

The U.S. Anti-Doping Agency said DuPree tested positive in March at the USA Indoor Combined Events meet for the asthma medication Salbutamol, which is allowed only with an exemption.

USADA and the U.S. Olympic Committee have been working hard over the past few months to make sure American athletes have updated their exemptions for the Olympics in Beijing, where some athletes expect pollution to trigger more asthma problems.

DuPree was stripped of her third-place finish in the pentathlon at the indoor meet in March but didn't receive any other sanction.

She is one of 18 women trying for three Olympic spots beginning Friday at the trials.
