After returning from four weeks of rehabilitation in Malibu, California, for substance abuse, Cousins was offered an amended contract by West Coast, rumoured to contain strict conditions such as repaying the cost of rehab and undertaking regular drug tests. On 29 June 2007, Cousins was given clearance by the AFL to resume training with the West Coast Eagles, which he did the following Monday. However, he injured a hamstring in training, delaying his comeback until West Coast's home game against Sydney on 21 July at Subiaco Oval. He gained 38 disposals and six marks in the game, inspiring West Coast's win.
