AFL integrity chief Andrew Dillon spoke to the media on Thursday regarding the issue.

He has been suspended under assertion of “urine substitution”, Dillon said from a press conference in Melbourne.

“The provisional suspension will last until the matter is determined.”

The test was taken on August 20 of this year.

In a statement late Thursday afternoon The West Coast Eagles said: "The West Coast Eagles have been made aware that Willie Rioli is the subject of an ASADA and AFL investigation.

"The club is extremely disappointed that one of our players has been provisionally suspended while a matter is being investigated and it will comply fully and openly with ASADA and the AFL through the process.

"The club is fully committed to supporting Willie during what is a personally distressing time.

"Our primary concern is Willie’s health and welfare.

"The West Coast Eagles fully supports the AFL and ASADA in its ideal of our game being drug-free."

More to come.
