Collingwood have been fined $20,000 for what the AFL has labelled an administrative error regarding the league’s player rules.

AFL football operations manager Adrian Anderson said on Thursday the league’s investigations manager Ken Wood found the Magpies had breached the Total Player Payment (TPP) lodgement rules through an administrative error by failing to lodge two player agreements for additional services within the required timeframe.

The value of the agreements has been included in the club’s 2012 TPP and has not caused the club to breach the TPP limit, Anderson said in a statement.

Anderson said Collingwood voluntarily advised the AFL of all the required information. He said the Magpies had implemented improved administrative procedures and the club’s full cooperation had been taken into account regarding the penalty.
