CELTIC have taken up the option to postpone a match in January to have a mini-winter break.
Kilmarnock's visit to Parkhead has been moved back to a midweek date, meaning Celtic will not play between January 5 and 18.
A statement from the league read: "The Scottish Premiership match between Celtic and Kilmarnock, scheduled for Saturday January 11, has been rearranged for Wednesday January 29 after the SPFL board agreed to a request from Celtic."
Premiership clubs agreed in June last year that they would be able to postpone games on January 11 or 18 if they wished, in the absence of a winter break.
Celtic did not look in need of a rest when they tore Hearts apart in a 7-0 William Hill Scottish Cup fourth-round triumph on Sunday.
First-team coach Danny McGrain (left) has seen and been involved in a number of classic Celtic displays and he watched in admiration as Neil Lennon's side raced to a five-goal half-time lead.
McGrain said: "everything just seemed to go right, everything was well-oiled and everyone seemed to be on the same wavelength, playing the ball and keeping the ball. It was just a great 90 minutes...
"Hearts could not keep pace with us and we just ran over them."
