Rugby league athlete receives sanction

15 April 2019

The Australian Sports Anti-Doping Authority (ASADA) today acknowledged the decision of the Australian Rugby League Commission (ARLC) Anti-Doping Tribunal to impose a two-year ban on athlete Kieran Tarrant for the use and possession of prohibited substances.

Mr Tarrant breached the sport’s anti-doping policy for the use and possession of Prohibited Substances, Clomifene citrate and Anastrozole.

Under category S4 of the World Anti-Doping Code Prohibited List 2014, Clomifene citrate and Anastrozole are prohibited both in- and out-of-competition.

Similar to other substances with anabolic properties that lead to increased muscle mass, clomiphene, an anti-estrogenic substance, is associated with a number of potential and serious side effects, including increased risk of negative cardiovascular events, liver damage, and gastrointestinal discomfort.

Anastrozole, an aromatase inhibitor and a treatment for breast cancer, can cause a loss of strength and energy, joint pain, hot flushes, headaches, and nausea.

The ARLC Anti-Doping Tribunal imposed a two-year ban on Mr Tarrant commencing on 30 July 2017.

Mr Tarrant is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 30 July 2019. He is also not permitted to compete in a non-Signatory professional league or Event organised by a non-Signatory event organisation.
