Marion Jones' 'B' sample negative; sprinter cleared

The backup drug test for sprinter Marion Jones came back negative, clearing the five-time Olympic champion of doping allegations that have dogged her for the past month, her attorneys said Wednesday night.

Jones tested positive for the banned endurance enhancer EPO on June 23. She withdrew from a meet in Switzerland last month and shortly after that, reports of a positive test were revealed.

The backup test, conducted at the same UCLA lab using the same sample, came back negative, however, meaning the 30-year-old sprinter has been cleared of any wrongdoing. She faced a minimum two-year ban.
