On 16 October 2007, Cousins' car was stopped in Northbridge and searched. He was arrested for drug possession and refusing to submit to a blood test. The Eagles sacked him the next day, which meant that he was no longer a registered AFL player. On 19 November, he was banned from playing senior football for 12 months by the AFL Commission for "bringing the game into disrepute", and was formally delisted by West Coast on 30 November. Eagles officials said that he would never appear in an Eagles guernsey again, and AFL CEO Andrew Demetriou said it would be "extremely difficult" for him to ever return to the AFL.
