Livingston's clash with Dundee was called off following the failure of the undersoil heating at Almondvale. It was fixed yesterday morning but the pitch was deemed too hard following a 2.15pm inspection. Another attempt to play the match will be made this evening, with the winners set for a fifth-round clash against Ayr United.
Raith Rovers' tie with Airdrie United also failed a 2.15pm inspection yesterday afternoon after the bottom end of the surface at Stark's Park was deemed to be frozen. The two First Division sides will try again on Monday, with a home tie against Aberdeen the prize for the winners.
The call-off at Stark's Park means that Raith's league match with Dunfermline, which was scheduled for next Tuesday night, has been postponed. No new date has been confirmed yet.
