Shamrock Rovers will hope to claim their first FAI Cup title since 1987 when they face Fanad United at Dalymount Park.
But they will be without four key men for the clash with Keith Doyle and Brian McGovern injured, and Trevor Molloy and Pat McCourt suspended.
Fanad United are without Fergus Callaghan (knee), Shane Sweeney (hamstring) and Martin McAteer (suspended), while Seamus Friel emigrated to the USA at the end of the Ulster Senior League season.
