Four clubs have been sanctioned by the AFL for breaching the ASADA code.

The clubs were fined for failing to disclose the location of their players during the off-season for drug testing.

Carlton were handed the hardest fine of $10,000, Melbourne were fined $5,000 and the Western Bulldogs and Richmond were both sanctioned $5,000 for the code breach.

The club’s breached the AFL’s drug testing policy in conjunction with ASADA.

Players are provided with a phone app where they must keep their locations available to clubs, with failure to do so resulting in sanctions.

The Tigers were previously involved in a similar incident in December 2017 where they were fined $5,000.
