Pratt was rookie-listed for 2003 by the Brisbane Lions; a serious hand injury in mid-season required surgery resulting in no further games in 2003.

In 2006, Pratt played 18 games but chose to end his season after surgery which would enable him to start pre-season training with the team in October.

[2] With no offers from any AFL club forthcoming, Pratt accepted a two-year contract with the Box Hill Hawks.

Pratt joined West Coast as a development coach in 2014, filling the void left by Adrian Hickmott, who was promoted to a senior assistant role at the Eagles.

Pratt worked alongside former AFL players Luke Brennan and Luke Ablett to help develop and educate a Respect and Responsibility program which was deliverable to AFL, State League and Community Footballers during this period to build awareness and education on social issues.

This included modules around building Respectful Relationships with Women, as well as an Illicit Drug and Alcohol component for better understanding of the effects of these issues and the damage they cause within the community.
