Outgoing World Anti-Doping Agency president John Fahey said charges against Bombers players were imminent in an interview with the Australian Financial Review on Friday.

He said: "I expect there will be several charges laid by ASADA. It's only a matter of when."

However, he backed away from those comments on Saturday, telling The Weekend Australian he had no specific knowledge on which he had based those claims.

Essendon chairman Paul Little said the club had contacted the AFL and ASADA to seek clarification on potential infraction notices to its players. 

"Last time these issues were raised we made our enquiries through the AFL and ASADA and again those enquiries have indicated to us that there are no new issues that we need to be advised about," Little told essendonfc.com.au on Saturday.

"We are sincerely sorry for the trauma that these constant comment are causing to all of us but at this point in time we don’t have any information to suggest anything has changed in relation to those allegations."

In relation to infraction notices against Essendon players, Fahey said: "I have no knowledge nor do I want it".

"I have had some general discussions at different stages over the past year with different personnel, none of which have had any detail in it," he said.  

"I steadfastly refuse to accept detail.

"It has always been my understanding that when they finish their investigation there is a strong likelihood that action will be taken.

"I have learned nothing in recent weeks to suggest one way or another that is correct or incorrect. It has just been my understanding for a long time."
