ADELAIDE Football Club has been fined $20,000 for a breach of the AFL Player Rules, with half the sanction suspended until October 31, 2009.

AFL football operations general manager Adrian Anderson made the announcement on Friday night, and said the Crows voluntarily disclosed the breaches as soon as they were discovered.

The AFL's investigations manager Ken Wood found that the club had failed to lodge arrangements between a player and associates of the club within the required timeframes, as required by the Total Player Payment (TPP) rules.

Mr Wood confirmed the Adelaide Football Club voluntarily advised the league and its full co-operation had been taken into account regarding the sanction.
