Paul Osam's Under 21 team will face either Bohemians or Drogheda next Tuesday night at Richmond Park in the League Quarter-finals.
Drogheda must replay their game against Mullingar this Saturday and will qualify to meet the Saints if they win by a 5 goal margin.
If they do not achieve that margin Bohemians will provide the opposition in Inchicore.
Kick-off is scheduled for 7.45pm
