Willie Collum has been appointed as the official for Sunday's Scottish Premiership clash between Kilmarnock and Rangers.
The whistler will take charge of the game assisted by linesmen Alan Mulvanny and Dougie Potter, along with fourth official Andrew Dallas.
The game will be Angelo Alessio's first league game in charge of Kilmarnock and he will see it as a good test to see where his side are at.
Steven Gerrard goes into the game full of optimism as his side have been performing well in pre-season and in the Europa League.
