Debuting with the West Coast Eagles in 2000, Green was used as a utility/defender and was always on the fringes of selection.
He played just six games in each of his first two seasons, before having a solid year in 2003 where he managed to hold his spot in the side.
In the 2005 AFL Draft, Green was selected by the Kangaroos after being delisted by the Eagles.
He was never much of a major ball winner at the Kangaroos, although Green showed the Roos faithful just how much of a booming running kick for goal he had, as shown by good examples against Hawthorn in round 6 and Collingwood in round 22.
On 27 September 2007 he announced his retirement from the AFL and returned to captain East Fremantle in the WAFL.
