Alan Muir will referee Saturday’s potential title clincher between Kilmarnock and Celtic.
The 36-year-old has only been in charge of two Celtic matches so far this season, at home to Motherwell in September and the Scottish Cup tie with Peterhead in January.
On Saturday he was the man in the middle at Hampden for Queens Park’s 1-0 defeat from Peterhead.
Celtic’s Scottish Cup semi-final with Hearts on April 15 will be refereed by Euan Norris with Willie Collum in charge of the other semi-final between Hibs and Aberdeen.
Norris was also in charge of Celtic’s League Cup semi-final against Falkirk.
