WILLIE COLLUM will be in charge of Celtic’s crucial Premiership game against Giovanni van Bronckhorst’s side at Ibrox on Sunday.
He will be assisted by Graeme Stewart and David Roome on the touchlines with Nick Walsh the fourth official.
Kevin Clancy was the referee in the first derby of the campaign when Ange Postecoglou’s new-look side unluckily lost 1-0 at Ibrox in late August.
Bobby Madden took over the duties for the return at Parkhead in February when a double from Reo Hatate, making his debut in this fixture, and one from Liel Abada gave the hosts a 3-0 triumph.
Now all eyes are on Collum in Govan this weekend where a win for the Hoops will send them six points clear with only six games to play, one of them at Parkhead after the split.
Ange Postecoglou’s men also enjoy a plus-14 goal difference in the club’s bid for their tenth championship in 11 seasons.
