The AFL has fined Collingwood and Fremantle after players from the two clubs had failed to provide up-to-date drug testing information.
The league announced on Friday that three Magpies players and two from the Dockers had not kept their clubs informed of their movements and contact details.
The whereabouts information is a key feature of the standard anti-doping code, where players can be tested at any time.
Under the AFL's agreement with ASADA, the club and not the player is punished if the whereabouts information is not up to date.
Collingwood were fined $7500 and Fremantle received a $5000 penalty.
