Shayna Jack suffers brutal $7 million blow over doping scandal

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

Jack was selected last month to compete for the Cali Condors team during the ISL season that starts in October.

However the league has established a zero tolerance policy regarding doping.

‘PIECE OF TRASH’: Vile, disturbing twist in Shayna Jack scandal

The ISL said Monday that Jack's suspension was in effect while the Australian Sports Anti-Doping Agency investigates.

Andrea di Nino, managing director of the ISL, said any athletes with doping control or ethical violation records will be considered ineligible with no recourse.

“No doping control rules violation will be overlooked,” said di Nino.

“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.”

It means Jack will miss out on a potential slice of the staggering prize pool on offer for competitors.

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 looks to be facing a lifetime ban from the league, the punishment dished out to Brazilian sprinter Gabriel Da Silva Santos on Tuesday.

Santos, 23, tested positive to Clostebol - a synthetic androgenic steroid with anabolic effects - in June.

The 20-year-old swimmer said she tested positive for the substance Ligandrol, a substance she said can be found in contaminated supplements.

Jack has hired a lawyer and said she will fight to clear her name.

Coach confident Jack’s career not over

Swimming Australia head coach Jacco Verhaeren believes Jack can bounce back and save her career.

"Yes definitely (she can come back from this)," said Verhaeren, on arrival in Brisbane from the world swimming championships in South Korea.

"There are cases where the athlete's name is cleared, and it was all a mistake or contamination or whatever it was. And sure they come back from that."

Jack tested positive for the non-steroidal anabolic agent Ligandrol and must now state her case to ASADA.

Jack's coach Dean Boxall says he doesn't know how it happened but is standing by the 20-year-old as she tries to salvage her career.

"I stand by her," said Boxall, adding he didn't think the positive test overshadowed Australia's performance in Gwangju or affected the morale of her teammates.

"She's my swimmer and I believe in Shayna."

Boxall said he believed that the decision to withhold the information of Jack's positive test from the Australian swim team was the right one.
