Jones tests positive for EPOThe triple Olympics champion in 2000, Marion Jones, who is yet to recover from accusations of drug use, faced another crisis of her life after a positive test for erythropoietin taken at the US championships in Indianapolis.

Jones faces a two-year ban from athletics if the B sample confirms the A sample as revealed in the test conducted by the International Association of Athletics Federations.

The American sprinter left the hotel where the athletes were staying at 6am, reportedly “for personal reasons”.
