The SPFL have confirmed a series of fixture changes in Scotland's top flight after New Year.
Celtic's home clash with St Mirren and Rangers' trip to Ayrshire to face Killie are among the five amendments.
A combination of TV picks and the Viaplay Sports Cup semi-finals are the reasons behind the calendar switches.
On Sunday, January 8 there will be a double-header of Premiership action as Motherwell host Hibs at 1.30pm, before Rangers trip to Tannadice at 4pm.
The other three games have been moved due to the League Cup schedule the following weekend on Saturday 14 and Sunday 15.
The games concerned are Celtic vs St Mirren, Hearts against Aberdeen at Tynecastle and Kilmarnock vs Rangers.
The latter match has been selected by Sky for TV coverage.
