Sporting Fingal will mount their challenge for Airtricity League honours in 2011 playing their home fixtures at Dalymount Park.
The Dublin club completed their first season in the country’s top flight in 2010 with a very credible fourth place finish, five points behind champions Shamrock Rovers.
Liam Buckley’s side have been based in Santry’s Morton Stadium since they took up membership of the League of Ireland 2008.
Sporting secretary John O'Brien said: ‘After three years competing in the Airtricity League of Ireland, we felt it appropriate to carry out an appraisal of our overall operation.
‘We are immensely grateful for having had access to Morton Stadium since our birth. At this point in our existence, however, we have to plan the next phase of our development.
‘While there may be some disappointment amongst our supporters at this decision to move, another consideration for us is the accessibility of Morton for our overall catchment. This arrangement does not affect our medium term plans to develop our own ground at Lusk.’
Fingal manager Liam Buckley added: ‘While we are thankful to Morton Stadium for having use of the venue in our formative years and hold many great memories from our time in Santry, we are looking forward to playing our matches in Dalymount Park for the next three seasons.
‘From a football perspective, too, Dalymount is acknowledged as having the best playing surface in the Airtricity League which lends itself to the team’s style of play.’
Sporting have signed a three-year agreement with Bohemians FC to use Dalymount Park for their home games from next season.
