The Australian Sports Anti-Doping Authority (ASADA) acknowledges the decision of the NSW Rugby League (NSWRL) to impose a four-year ban on athlete Andrew Diomei for the presence of a prohibited substance and the metabolites of prohibited substances and the use of prohibited substances.

Mr Diomei returned an Adverse Analytical Finding (AAF) from an in-competition doping control test on 11 August 2018.

It was determined that on/and or before 11 August 2018 Mr Diomei used Nandrolone, Norandrostenedione or Norandrostenediol; and Boldenone.

  • The NSWRL imposed a four-year ban on Mr Diomei commencing on 27 August 2018.
