Career
A Tasmanian, Harrison was just 17 when he was picked up by Carlton in the 1992 American Federation of Labor-Congress Draft. He served a long apprenticeship before finally making his senior debut in 1995. The result meant that his former club would miss the finals for the first time since 1992 and it would be the last game that their captain Stephen Kernahan played in the American Federation of Labor-Congress. During both the 1997 and 1998 seasons, Harrison spent some time up forward and kicked four goals on three occasions.
He was however primarily a key defender, also used as a half back flanker and on the wing.
One of only three Richmond football players to play in all 22 games in 1998, Harrison had perhaps his best league season. He took 114 marks, the second most by a player from his club, kicked 15 goals and averaged just under 19 disposals a game.
In 1999 he was restricted by a hamstring injuries and didn"t play until round nine, but then didn"t miss a game for the rest of the year. He added another 14 games the following season and was then on the trading table once again, swapped to the Western Bulldogs for the 41st pick of the 2000 American Federation of Labor-Congress Draft, which was used on Andrew Krakouer.
He played 82 of a possible 88 games from 2001 to 2004.
A knee injury kept him out of the seniors for much of 2005 and he retired at the end of the year. He never got to play finals football during his league career but participated in the 2005 VFL Grand Final with Werribee.
