Following retirement, Morrison became assistant manager of Bury, later having a similar role at Northwich Victoria and Airbus UK Broughton.
At the age of 13, Morrison had a trial at Southampton along with 39 other hopefuls including Alan Shearer, Tim Flowers and Matt Le Tissier.
He made his Football League debut as a substitute in a 5–2 defeat at Aston Villa, in 1987, in which David Platt scored the winning goal.
An uncompromising centre-half with a broad Plymothian accent, Morrison scored his first senior goal in a 1–0 win at home to Ipswich Town in March 1990.
[2] Morrison spent one final season at Home Park following the club's relegation from the second tier in 1992, before Shilton accepted a £500,000 offer from Blackburn Rovers, then managed by Kenny Dalglish.
[6] Morrison also played for Blackburn's reserve team, alongside Shay Given and former Plymouth teammate Nicky Marker.
[7] Morrison was unable to break into the Rovers side on a regular basis, as he faced competition from Colin Hendry, Henning Berg and Ian Pearce.
He was an unused substitute in the 1994 FA Charity Shield in which Blackburn were beaten 2–0 by Manchester United after goals from Eric Cantona and Paul Ince.
In the 1997–98 season, Morrison played in Huddersfield's 3–0 defeat to West Ham United in the League Cup, in which John Hartson scored a hat trick.
[23] He also played in Huddersfield's second win of the season, a 1–0 victory against Manchester City at Maine Road, in which Rob Edwards scored the winner.
[36] Collymore mentioned the incident in his autobiography, stating that Morrison 'stuck his tongue in my mouth' and that he was one of three players (along with Andy Todd and Darren Purse) who sought to 'prove that they were real hard men when they were up against me'.
Brown was reportedly interested in calling Morrison up to the international team to play in the UEFA Euro 2000 qualifying play-offs against England.
Morrison spent 14 months attempting to return to the Manchester City team, even requesting that Royle loan him out to his former club Blackpool[41] who were managed by Steve McMahon at the time.
[43] Morrison then joined Crystal Palace (then managed by Alan Smith), on a months loan in October 2000,[44] to continue improving his match fitness.
[53] Morrison's absence had prompted Royle to sign Spencer Prior to help City earn promotion, and subsequently Steve Howey and Richard Dunne to help the team stay in the top flight.
Shaun Goater contended that City 'missed Andy Morrison's presence that season' and that 'with his motivational skills things might have turned out differently'.
Keegan hoped that Morrison could provide leadership in the dressing room to address the drinking culture at the club, but lamented that he 'couldn't get him in the team' (due to his continuing injury woes), which led to the signing of Stuart Pearce.
[75][76] Morrison ultimately failed to recover from the injury that he sustained while he was at Sheffield United and he was released by the club at the end of the season.
[81] Some feel that it was Morrison's leadership skills and ability to get the players around him to raise their game that enabled Manchester City to return to the Premier League after their fall into Division Two.
In an interview with the BBC on 23 September 2005, Joe Royle spoke of his sympathy for Nottingham Forest, a club which, like Manchester City, had fallen two divisions.
During a pre-season friendly match against Kidderminster Harriers on 5 August 2006, an incident in the changing-room area caused the game to be abandoned after 71 minutes.
Harriers' manager Mark Yates called the referee over to him and said he was going to take his team off due to an off-the-field incident involving Morrison.
The club fined Morrison the maximum allowed under FA guidelines, suspended him for three games, and warned him of his future conduct.
In fact, they had appointed Andrew Amers-Morrison who was visiting the country on holiday and whom the Seychellois football officials mistakenly believed was Andy Morrison.
[85] Suketu Patel, chairman of the Seychelles Football Federation (SFF) conceded that "we thought we were getting the real Andy Morrison".
[87] The SFF sacked Andrew Amers-Morrison two weeks later because they "could no longer be certain if he was still the right person to head the coaching staff of the national team".
In 2016, Morrison won the 20th edition of the Footballers' Golf Classic at the world-famous La Manga Club in Spain, defeating his former boss Kenny Dalglish in the process.
[94] The Nomads were the first non-Scottish side to reach the Scottish Challenge Cup Final,[95] but lost to 3-1 Ross County on 23 March 2019.
He failed to inform the Department for Work and Pensions and Vale Royal Borough Council in Cheshire that he had £58,000 in his bank account while he was still claiming benefits.
[98] Morrison was inducted into the Hall of Fame at Bloomfield Road when it was officially opened by former Blackpool player Jimmy Armfield in April 2006.
