WADA chief John Fahey says Essendon 'still under investigation' from anti-doping agencies World Anti-Doping Agency president John Fahey. THE Essendon supplements saga may yet have "a few chapters" to play out, with outgoing World Anti-Doping Agency boss John Fahey warning the AFL club could yet face sanctions. There has been ongoing speculation that despite the club being heavily sanctioned by the AFL, the Bombers could also face infraction notices - from anti-doping agencies - to both players and officials in the off-season. Late last month AFL deputy chief executive Gillon McLachlan said he had no knowledge of any impending fraction notices . However Fahey, speaking to ABC, said the Essendon case may not be over. While reluctant to give his view or his opinion on the AFL's penalties to the club, he said people needed to be patient, saying "we've still got a few chapters to read on this one before it's finished." " (They're) nothing to do with anti-doping whatsoever," Fahey said of the Bombers' penalties. They're all to do with the code of conduct the AFL has. Anti-doping is still under investigation and there will be events there as I understand it that will unfold in the months ahead. But that will happen when ASADA is ready. So what the AFL has done they have done under their own code of conduct (and) I make no comment there. AFL CEO Andrew Demetriou and chairman Mike Fitzpatrick announce Essendon's penalties at a press conference in August. In late August the league punished the Bombers over its governance failures, fining them $2 million, suspending coach James Hird for 12 months and banning them from the 2013 finals. Essendon football manager Danny Corcoran received a ban of six months (two months suspended) while assistant Mark Thompson - who has since become senior coach in Hird's absence - was fined $30,000. Well I'm not sure whether James Hird will be dealt with by ASADA. That's possible before it's all over, so what's happened to Essendon ... has had nothing to do with ASADA's rules or the rules I'm responsible for as president of that body (WADA). So I've got to hold my fire until we've finished, until ASADA - a constituent member of WADA - concludes its inquiries and deals with the case in accordance with the code, and that may be some time yet.
