Rangers v Livingston and Motherwell v St Mirren in the Premiership are among four Saturday Scottish fixtures postponed because of wet weather.
Hearts v Hamilton Academical and Ross County v St Johnstone, both at 15:00 GMT, are expected to go ahead.
Two more top-flight games are scheduled for Sunday.
Ayr United v Greenock Morton in the Championship and Brechin City v Annan Athletic in League Two were called off earlier on Saturday.
On Sunday, Premiership leaders Celtic travel to take on Aberdeen at 12:00 and victory for Neil Lennon’s side would take them 13 points clear of Rangers, having played two games more. Rangers v St Johnstone, postponed earlier this season, is yet to be rearranged.
Kilmarnock host Hibernian at 16:30 on Sunday.
Motherwell are scheduled to meet St Mirren at Fir Park in Tuesday’s Scottish Cup replay and Rangers’ next match is at home to Europa League last-32 opponents Braga on Thursday.
