The AFL has fined GWS $10,000 for an embarrassing anti-doping mistake.
The Giants were left red-faced after they failed to keep ASADA briefed properly on players’ addresses.
Under the anti-doping code, players can be tested throughout the year and the whereabouts provision is a critical feature of the testing regime.
News of the blunder comes only five days before the AFL anti-doping tribunal hands down its verdicts on 34 current and past Essendon players.
“All clubs have a requirement to be fully compliant with all the paperwork requirements of the Anti-Doping Code to ensure that ASADA is fully informed at all times and can perform its duties,” AFL general counsel Andrew Dillon said in a statement.
“In this instance, it is important that the rules are fully complied with and a financial sanction is appropriate.”
GWS football operations manager Graeme Allan said the club took responsibility for the error.
“We have a strong commitment to upholding and adhering to the games integrity framework,” he said.
“But we acknowledge that a basic administrative error has resulted in player addresses not being communicated properly.”
