The AFL is about to announce a revamped illicit drugs policy that will carry tougher penalties for players who return positive tests.
AFL football operations manager Mark Evans and AFL Players Association chief executive Paul Marsh will hold a media conference at league headquarters from 3.30pm.
According to media reports, players who incur a second strike for illicit drug use will now receive a four-week ban and a $5000 fine.
Previously, the identity of players remained anonymous until their third strike, when players then received a $5000 fine and possible suspension.
Now, a third offence will constitute a 12-week ban and $10,000 fine.
Players who test positive from hair samples will still not register a strike, while first time offenders will still only receive a suspended fine while going unnamed.
