Australian swimmer Shayna Jack hit with maximum four-year ban for failed drug test.

Australia’s Shayna Jack has been banned from the rich International Swimming League as she prepares to fight her doping case.

Jack had been included in the Cali Condors team for the ISL’s series starting this October.

But the ISL says Jack has been suspended from the league, pending the outcome of her doping case.

Jack will on Friday meet with Australian Sports Anti-Doping Authority (ASADA) after testing positive for a banned drug earlier this month.

It’s believed the 20-year-old faces the maximum four-year ban for testing positive to the banned drug Ligandrol, unless she can prove her innocence.

“You’ve got positive A and positive B sample and the process is you get a letter, you will be suspended, then you have right to request a tribunal hearing with the Court Arbitration for Sport,” former ASADA boss Richard Ings told The Daily Telegraph.

“I wouldn’t draw any conclusion from the four-year ban, that happens in every matter. The issuing of notification of a four-year ban is standard practice in all these matters.”

The 20-year-old had been selected for the ISL, a new series of events featuring some of the world’s best swimmers.

The ISL’s managing director Andrea di Nino says Jack’s selection has been revoked for the meets to be held in Europe and the United States from October.

“No doping control rules violation will be overlooked,” di Nino said in a staement on the ISL’s website.

“This is another case that serves to reiterate our stance on banned substances and breaking doping control rules. No such behaviour will ever be condoned.

“From the outset, the ISL has been an advocate for transparency and clean sport.

“Any athletes with doping control or ethical violation records will be considered ineligible with no recourse.”

The ISL has been founded and funded by Ukrainian billionaire and swimming fan Konstantin Grigorishin, who has earmarked a $US20 million budget for the initial series, of which $7m will go to swimmers and teams in prize money.

Jack has tested positive for the banned drug Ligandrol, a muscle growth agent, during an Australian swim camp ahead of the world championships in South Korea.

She withdrew from the world titles, initially citing personal reasons, only for her positive drugs test to be revealed last weekend.

Jack has denied knowingly taking any banned substance and will plead her case to ASADA in Canberra on Friday.

Jack's manager Philip Stoneman said the swimmer wouldn't contest the presence of the banned drug in her system.

"I don't think this is a question of Shayna denying there is something in her body," Stoneman said on Monday.

"What she is doing is fighting her innocence because it shouldn't be in there and she doesn't know how it got in there."
