Australian swimmer Shayna Jack has reportedly tested positive to a banned substance.
The 20-year-old mysteriously withdrew from the World Swimming Championships in Korea just days out from the meet.
She initially attributed her departure to “personal reasons”.
But Jack, who shares a coach with superstar Ariarne Titmus, returned an abnormal ‘A’ sample during routine testing at a pre-Worlds training camp in Japan a fortnight ago.

The 20-year-old Jack confirmed the positive test result on Saturday but claimed she did not “knowingly” ingest a banned substance.
“Swimming has been my passion since I was 10 years old and I would never intentionally take a banned substance that would disrespect my sport and jeopardise my career,” Jack told The Sunday Telegraph.
“Now there is an ongoing investigation and my team and I are doing everything we can to find out when and how this substance has come into contact with my body.”
The news comes after a week of stunning anti-doping protests against the China at the worlds, with Australians among the most vocal against doping-implicated swimmer Sun Yang.
Jack’s teammate Mack Horton made international headlines when he refused to share the podium with Chinese megastar Sun Yang after the 400m freestyle final.
Yang, who lives and trains on the Gold Coast, tested positive to the stimulant trimadazidine in 2014.
He is also set to face a hearing with the Court of Arbitration for Sport (CAS) over allegations he smashed blood vials when visited at his home by drug testers last year.
MORE TO COME.
