Payne outed for four weeks over positive

Melbourne Cup-winning jockey Michelle Payne has been outed for a month after returning a positive to a banned appetite suppressant.

Payne was prescribed Phentermine by her doctor to treat gastrointestinal problems, connected to injuries sustained in a fall last year.

The positive result is from a sample taken at the Swan Hill Cup meeting on June 11.

She was stood down from riding in races and trackwork from June 23.
