Willie Collum has been named the referee for this weekend's Rangers vs Celtic clash.
The whistler has led the game a number of times throughout his career.
His last match officiated between the two was back in May 2021 when Rangers ran riot in a 4-1 win over their fierce rivals.
He is to be assisted by Graeme Stewart and David Roome with Nick Walsh the fourth official.
The match could potentially go a long way towards where the Premiership title ends up in May.
A Celtic win would take them six points clear while Gers would go level with three points.
Only a handful of whistlers would likely have been considered to take the big one including John Beaton and Bobby Madden.
The latter was centre-stage back in February when Celts ran out 3-0 winners at Parkhead.
