Career
Seamus also played as a goalkeeper for Offaly minor team in 1992. Seamus signed for University College Dublin in the summer of 1993, making his League of Ireland debut on 19 September, from hometown club Tullamore Town and established himself as one of the league"s best keepers before joining Cardiff City in 1998 as cover for Jon Hallworth. Kelly began his Cardiff career on the bench but was called upon at the end of the 1998-1999 season when Hallworth broke two ribs in a match against Leyton Orient.
The following season saw the same scenario at the opposite end of the table as Kelly played in the final six matches of the year but was unable to help the club avoid relegation, being released at the end of the season.
Kelly returned to Dublin to sign for Street Patrick"s Athletic. After 3 seasons in Inchicore, Stephen Kenny took him to Bohemians where he challenged for the #1 spot with Matt Gregg.
Kelly was first choice during Bohemians" Union of European Football Associations Champions League campaign in 2003 but never made the goalkeeping spot his own during his time at Dalymount Park. Kelly joined Longford Town from Bohs in 2005 and played a crucial role in the club"s FAI Cup run in 2007 and also their gallant battle against relegation that same season.
Due to persistent back problems, Kelly retired during the summer of 2008.
In 2010 he became Goalkeeping coach with Sheloburne.
