Crow was recruited from the Oakleigh Chargers of the TAC Cup, but from Doncaster originally.[1] In 2004 he made just one AFL appearance, in Collingwood's round 19 win over Fremantle at Subiaco Oval.[2] He took two marks and had two kicks in the win. After leaving Collingwood he continued playing football with the Northern Bullants.[2] Despite his minimal number of games for the senior team, Crow was the first Collingwood player to twice win the Joseph Wren Memorial Trophy for the best and fairest in the VFL team.
In 2013 Justin became the acting fitness coach at Essendon Football Club.
