2019 FINA WORLD AQUATICS CHAMPIONSHIPS
Just days before the start of this FINA World Championship, Australian freestyle pilot announced her sudden retirement from the world's largest non-Olympics swimming event.  As we reported on June 14, Jack explained through her social media, "For personal reasons, I have to retire from the World Cup with great sadness." This was confirmed as the 2017 World Cup medalist tested positive for a banned substance.
Once again on Instagram, Jack reveals that she tested positive, saying, "I would never purposely take a banned substance that disregards my sport and my health jeopardize my career. "
The St. Peters Western athlete continues," Now there is an ongoing investigation and my team and I are doing everything to find out when it is possible. Now the substance has come into contact with my body.
The exact substance has yet to be announced, but the Australian Sports Anti-Doping Authority (ASADA) states that the drug test was conducted on June 26th. Jack is suspended for the time being as the investigation begins.
According to Swimming Australia, Swimming Australia and WADA, as well as FINA, will be notified of any negative test results under specific Australian drug testing laws. As part of the process, all details must be kept confidential until ASADA has completed its investigations, the athlete has received the due process and has found a result.
Leigh Russell, CEO of Swimming Australia explains, "Swimming Australia is and has always been committed to clean sport. We have consistently advocated a zero-tolerance approach to doping and have backed a rigorous and consistent approach to drug testing both here and overseas.
"According to our system, swimmers will automatically get a negative test if they repeat it. Preliminary suspension and cessation of the contest until the ASADA process is completed and the result determined.
"As expected, we are bitterly disappointed by the allegations that a swimmer has a banned substance in her system, although it is important to point out that the matter remains to be resolved. We will continue to support Shayna properly. We will also support our team members who are still in Korea, and our team and organization will continue to reaffirm our zero tolerance approach. "
In this year's World Cup, two swimmers have already refused to stand on the podium of China Sun Yang the man who seeks a public hearing of the CAS this fall. One of the men who refused to recognize Sun in photographs was Mack Horton from Australia, who says sport has no room for drug addicts, even though his compatriot is now in the limelight.
Regarding the International In the Swimming League (ISL), Jack has been named Cali Condors in the US, and their status is now potentially jeopardized by this news. The league was very vocal in terms of zero tolerance, a policy that precluded earlier positive testers like the aforementioned Sun and Russian Yuliya Efimova, but also rejected non-positive testers like Thomas Fraser-Holmes.
