Career
He was unable to make any senior appearances for the West Coast Eagles, due to a knee injury. Collingwood gave up the 12th selection of the 1994 American Federation of Labor-Congress Draft to secure Walker, a pick which the Eagles used on Shane Sikora. He continued to be hampered by injuries at Collingwood but was able to play 16 American Federation of Labor-Congress games in three seasons.
A key position player, he had a total of three knee reconstructions during his career.
After being delisted he nominated for the 1998 American Federation of Labor-Congress Draft and was re-signed by Collingwood, but he would only play reserves matches. Since retiring, Walker has remained involved in football as both a Player Development Manager and as a player manager.
