He attracted the interest of Manchester City during his time at Shels.
Byrne signed for Shamrock Rovers in the summer of 1984.
In each of his three seasons at Milltown he won the domestic double as well as representing the League in the Olympic qualifiers. He was the top scorer in the 1986–87 League of Ireland Premier Division season  and made 6 appearances in European competition. Transfer talks with AS Saint-Étienne and Feyenoord didn't work out so after 72 goals in 146 games, in January 1988 Mick signed for FC Den Haag thus ending an extraordinarily successful period at Rovers.
He briefly re-signed for Rovers again in July 1988 but after 3 goals in 6 games he left for Huddersfield Town A.F.C. the following month for £20,000. After two seasons in which he scored 11 goals in 56 league games, he came back to Rovers for the club's first season in the RDS but left in January 1991 after 5 goals in 20 appearances for Sligo Rovers as the club had an abundance of strikers. At Sligo he scored 6 goals in 34 total appearances, 27 in the league.
He had two more spells at Shels and also represented Dundalk F.C., Monaghan United, St. James's Gate F.C. (one game) and Athlone Town during his career. With Monaghan he finished was the 1992–93 League of Ireland First Division top scorer and his 15 league goals helped them gain promotion.
He was Rovers top goalscorer in 1984/85, 1986/87 and 1987/88 and made 5 appearances in Europe.
In 1996 he managed St. James's Gate F.C. for two games, playing once, before their resignation from the league. He then returned to Rovers as assistant manager to Pat Byrne before taking over as the manager for the 1997/98 season. In his first season in charge he guided the club to a win in Europe but his second season ended badly as Rovers finished 8th. He was replaced by Damien Richardson.
