The AFL has confirmed that William Rioli of the West Coast Eagles has been notified of a further Adverse Analytical Finding (AAF) and a potential violation of the Australian Football Anti-Doping Code (Code) in respect of a test conducted by ASADA on September 5, 2019.
The test was conducted following the West Coast Eagles’ elimination final against Essendon.
The September 5, 2019 sample has tested positive for a metabolite of cannabis, which is an In-Competition Prohibited Substance under the Code.
On September 11, 2019 Rioli was notified of an Adverse Analytical Finding for Urine Substitution being a Prohibited Method under the Code following an Out-of-Competition doping control test on 20 August 2019.  
The West Coast Eagles have been made aware of this finding and will continue to provide support for Rioli.
It is important that Rioli be provided a fair process.  As a result, the AFL will not be providing further detail on this case at this time.
