Eamonn Collins, who had appeared in professional football for Blackpool before his 15th birthday, first played for Exeter City on loan from Portsmouth in 1987 ahead of returning to make a small number of appearances during the first half of 1992/93. He later managed Elmore and became a football agent in Ireland. 

Later to play for Ireland at youth and U-21 level, Eamonn became the youngest player to appear in a professional match in England when - in September 1980 - he played for Blackpool against Kilmarnock in the Anglo-Scottish Cup aged 14 years and 323 days. He then became an apprentice at Southampton, before signing professional in October 1983, and featured in three league matches prior to making the switch to Portsmouth in May 1986.

His first spell at Exeter City began in November 1987 when on loan from Pompey and, making his debut in the 2-1 home win against Stockport County, went on to make nine league appearances. After failing to break into the Portsmouth first team on a regular basis, he signed for Colchester United in May 1989 where he added two goals from 39 league starts.

Returning to Exeter on a free transfer in July 1992, Eamonn made 11 league appearances before moving to Farnborough Town in December 1992. Still based in Devon, he subsequently appeared for Minehead and Crediton United before switching to Elmore in February 1994 where he became player-manager until December 1996 through an often-controversial period during which the Tiverton club finished runners-up in the Western League.

In 1999 Eamonn joined Dublin club St Patrick's Athletic as assistant manager to Pat Dolan, succeeding him as manager in February 2003. However, despite a League of Ireland Cup win and an FAI Cup final appearance, Eamonn quit St Patrick's in May 2004 and joined Shelbourne as assistant to Pat Fenlon but was to leave following Fenlon's resignation in December 2006.

After leaving Shelbourne, Eamonn became a player agent and, through Pro10 Sports Management, became the Irish authorised ticket reseller for the Rio Olympics. In August 2016 Brazilian authorities issued arrest warrants for Eamonn and two other men as part of an investigation into alleged ticket touting. Denying any wrongdoing, little more was heard of Eamonn's involvement before the case was dropped in 2017.
