Jason Minett joined Norwich City as an associate schoolboy in June 1986 at the same time as Lee Power and Robert Ullathorne. All three had been part of Kit Carson's successful PGL England youth side. He turned professional in July 1989 and made his league debut as a substitute for Mark Bowen in a 3-0 defeat at Leeds in September 1990. Two more appearances were made but neither were successful, a 3-0 and 3-1 defeat. Injuries limited further opportunities and he joined Exeter City in March 1993. 88 appearances followed for the Devon side before he joined Lincoln in the summer of 1995. 46 league games and five goals for the Imps was followed by a return to Exeter on 17th January 1997. He made 13 appearances in the rest of the 1996/97 season.

Jason was released by Exeter in the summer of 1998 and he had trials with both Peterborough and Kettering Town. He joined Vauxhall Conference side Doncaster Rovers who also signed former Welsh international goalkeeper Neville Southall and former Irish international midfielder John Sheridan.

Doncaster released Jason on 10th May 2000 but a return to the conference is expected as The Non League Paper reported on 14th May that newly promoted Boston might sign Jason to strenghten their squad. This transfer was completed within 2 days of the story breaking. The following summer saw Jason transfer-listed by Boston in May 2001

Despite interest from other Conference sides, Jason opted for a return to Norfolk and signed for Tony Spearing's King's Lynn on 7th July 2001. He will be a direct replacement for Paul Raynor who left to become manager at Hednesford.

Jason was transfer listed by Lynn at the end of November 2001 along with Lee Hudson and Kristian Jones. All were made available on free transfers. Lynn's slide down the Dr Martens table prompted this action with manager Tony Spearing stating "I think for players who have come from the Conference they have not fulfilled what I expected from them.. I need them to come in and do extremely well... They are not cheap and I don't want them to be on a par with the rest..". Jason joined Stocksbridge on loan in January 2002. Jason returned to Lynn but joined Grantham Town on the Dr Martens League transfer deadline day in ealry April 2002. He helped the Gingerbreads to second place in the Dr Martens Southern and Eastern division winning them promotion whilst Lynn were relegated from the Dr Martens Premier Division.

In July 2004, Jason moved once again, joining Lincoln United. He returned to Grantham in July 2006 along with many of the Lincoln United team who followed manager John Wilkinson to the Gingerbreads.

Jason retired in the summer of 2008
