There's a tight window to get the game played, with the winners set to face Louth's Ardee on Saturday week
After the Leinster Club Football quarter-final between St Loman's and Castletown was postponed last night, fixture makers in Leinster GAA will meet today to find a new date for the game.
Heavy fog in Mullingar led to officials calling off the match two hours before throw-in due to poor visibility.
It's now likely to be played this weekend, with St Mary's Ardee awaiting the winners in the last-four on Saturday week.
