Galway United enjoyed a welcome break from league action and with the pressure off in Inchicore they duly delivered a 2-0 win thanks to goals from Jonah Ayunga and Eoin McCormack.
The Iveagh Grounds witnessed a tense encounter as Bangor Celtic from the Leinster Senior League frustrated Longford Town for over an hour.
