AFL chief executive Andrew Demetriou has urged any player that believes an opponent is using performance-enhancing drugs to contact the Australian Sports Anti-Doping Agency (ASADA) despite expressing disappointment at the latest drugs controversy to engulf the league.

ASADA is currently investigating claims by Western Bulldogs star Jason Akermanis that he suspected an opponent of using the stimulant EPO - which increases the oxygen carrying capacity of the blood - during a game at the Gabba in 2005 when he was playing with the Brisbane Lions.

While Akermanis did not name the player in question in his newspaper article, a West Coast player was subsequently named by Channel Seven with the Eagles and that players' manager Paul Connors now threatening legal action.

Demetriou said on Tuesday he was bitterly disappointed at the naming of the player and the way Akermanis chose to go about expressing his suspicions but yet urged other players who suspected opponents of using drugs to also act on their suspicions.

"Any player who has any information relating to any suspicion or allegation knows there is a hotline for ASADA that provides information," Demetriou said.

"If he (Akermanis) availed himself of that opportunity rather than doing it through an article, that would have been preferable but ASADA is now looking into it (Akermanis' claim) and we will see what they say."

Despite the league not having yet received a report from ASADA concerning its investigation into Akermanis' claims, Demetriou described them as 'without any foundation.'

"I am concerned about what is right and what is fair and I ask all the media to sit back and consider whether it is fair whether a player's name gets mentioned, his reputation gets tarnished and his family gets affected and then it sullies the reputations of many, many other players based on a suspicion that is without foundation."

"I don’t know what ASADA will find but this is a three-year-old claim that our understanding has no substance but ASADA will be the ultimate determinate of that."

Demetriou refused to say how many tests the AFL conducts for EPO or whether those tests will be increased in the wake of Akermanis's claims.

But he said he was proud of the AFL's record when it comes to the use of performance-enhancing drugs in the sport with only one positive test (Richmond's Justin Charles in 1997) recorded since testing began 15 years ago.

"We should be proud of the way AFL footballers and our coaches
