SNS GroupReferee Willie Collum will be in charge when Celtic play Rangers in the Scottish Cup semi-final on Sunday.
On Monday the SFA revealed their team of officials for both semi-final games that will be played at Hampden this weekend.
Collum’s assistant referees will be Daniel McFarlane and Dougie Potter with Don Robertson as the fourth official.
Steven McLean and Frank Connor will be in charge of VAR.
The game is massive for both clubs as the Hoops look to take another step closer to a domestic treble and their city rivals looking to avoid a trophy-less season.
There is now 13 points between the pair in the league with only five games to go – meaning Ange Postecoglou’s side only need another win to guarantee the title.
Rangers are yet to beat Celtic this season and have suffered three defeats from the previous four, including the League Cup final at Hampden, and only one draw coming at Ibrox at the start of the year.
The other semi-final between Falkirk and Inverness will be played on Saturday.
Nick Walsh will take charge of that game assisted by Calum Spence, Jonathan Bell and David Dickinson.
Alan Muir and Graeme Leslie will be on VAR.
