The AFL says none of their players are involved in the doping scandal which accuses nine Australian athletes of testing positive to a banned substance.

League corporate affairs manager Brian Walsh says the AFL would have been notified immediately by the Australian Sports Anti-Doping Authority had any player been involved.

But he said the AFL hadn't received any notification from ASADA that their players were among the nine athletes who have tested positive to the banned stimulant methylhexaneamine or DMAA.

"Under the ASADA performance enhancing drug protocols, any positive test of an A sample is immediately communicated to both the national sporting organisation and the athlete," Walsh said on Saturday.

"The AFL confirms that it has received no such communication from ASADA that any AFL player has tested positive to the prohibited stimulant methylhexaneamine.

"I don't know who they are but they are not ours.

"The process is if you have a positive to a banned substance then the national sporting organisation and the athlete are advised of it.

"And we have a very good relationship with ASADA, we're a blue-chip client of theirs and we've had no such notification so I think you can safely say it's not one of ours.

"They normally would notify the sporting body straight away as soon as they've got a positive of an A (blood) sample, before they see whether they want to test the B sample as well," Walsh said.

He said the drug scandal was "not an issue" for the AFL.

"I've run it past ASADA this morning and they're happy with it.

"If they had any notification that they'd just forgotten to tell us about then they had time last night and today.

"I've checked with all our guys who run our drug area and there's been no notification," Walsh said.
