Andy Brownrigg was described by then Norwich manager John Deehan as the next Dave Watson when he signed him from Hereford United for £100,000 in March 1995. However he failed to live up to these expectations and had not made a first team appearance for the Canaries by the time of his transfer to Rotherham in the summer of 1997. Indeed Andy spent part of his Norwich sojourn with the A team in the Essex and Herts Border Combination. To gain first team experience, Andy spent a month on loan to non-league Kettering Town during the 1995/96 season.

According to the March 1998 edition of Team Talk , Britain's most popular national non-league football monthly, Andy has since joined Stalybridge Celtic of the Vauxhall Conference on loan. Released by Rotherham in the 1998 close season, Andy joined Yeovil but parted company with them due to personal reasons. However the 1st November edition of Sport First revealed that Brownrigg was again playing for Stalybridge. There may be some confusion as to his whereabouts as the December edition of Team Talk magazine said Andy had joined Tamworth. The June 1999 edition of Team Talk reports that Andy is playing for Stocksbridge Park Steels of the Northern League.

In the summer of 1999, Andy signed for Jan Molby's Kidderminster Harriers. After a successful season that resulted in the Conference title and promotion to the football league, Andy was sold on 21st July 2000 to Scottish side Greenock Morton for £25,000. Andy was linked by the Unofficial Football Transfers website in November 2000 with a return to Kidderminster. This didn't materialise but in March 2001, Andy returned to English league football, joining Division 3 side Hartlepool . He was released in May 2001 without playing a single game. To date, Andy's only league appearances are 8 games for Hereford before his transfer to Carrow Road.

According to Teamtalk, Andy has approached Jan Molby about a return to Harriers where he was happiest. This didn't materialise and Andy joined Conference side Northwich Victoria in early June 2001. He moved to Hednesford in the autumn of 2001 and on to Gainsborough Trinity of the Northern League at the end of June 2002. He was released by Trinity towards the beginning of September 2002 and has since joined Wakefield & Emley.

In the summer of 2003, he trialled with Worksop. In November 2003, Andy played for Oxford United's reserves against their counterparts from Cheltenham. After a spell with Hallam, Andy joined Buxton in March 2005.

After another spell with Worksop, Andy signed for AFC Emley in July 2010. He has since retired

In a June 2011 interview with the Hereford Times, Andy revealed the extent of his addiction problems which led him to Tony Adams' Sporting Chances clinic. He has a first-class degree in sport and exercise psychology from the University of Huddersfield (2009) and is currently researching and writing a doctorate which explores the transitional experiences of professional footballers.
