No new date has been set, however it can't go ahead next Saturday. It is Scottish Cup Saturday and both sides are already out, however Saints have already arranged to take on Raith Rovers in another rearranged game.
This is the second time in just other 12 months this match has been postponed. At the tail end of 2002 the Saints were meant to meat at Love Street but it was postponed due to a, yup you've guessed it, frozen pitch.
