The SFA have confirmed the officiating team that will take charge of Celtic's Scottish Premiership clash against Aberdeen at Pittodrie.
Don Robertson will take the whistle as the on-field referee, and he will be assisted by Daniel McFarland and Colin Drummond as his linesmen. Grant Irvine will be the official on VAR, should a decision need to be made.
Robertson has already been the referee for five Celtic games this season. He was in charge for Flag Day, where Celtic beat St Mirren 1-0, and was also on the pitch for their 0-0 draw with Rangers.
His other matches were 0-0 against Hibs in September; 4-0 against Kilmarnock in November; and Celtic's 2-1 defeat to Hearts while Wilfried Nancy was in charge.
Fans preparing for the worst
After some of his refereeing performances, Celtic fans have labelled him a "disgrace", calling him out for decisions he made during the draw at Ibrox. Supporters noted that he seemed to be harsh on Celtic, with play being halted often while the Hoops were on the attack.
Sections of the support have noticed that Celtic seem to commit more fouls than the opposition most of the time, despite having a large share of possession. This usually isn't the case in football, leading some to believe that this is a deliberate pattern.
Celtic won't have to worry about getting a dodgy red card this time though, with the general consensus being that you'd need to attempt something extreme for Robertson to send you packing.
Martin O'Neill's side will be fighting for a third consecutive win after victories against FC Utrecht and Falkirk. Celtic will be hopeful of three points against an Aberdeen side in search of a new manager.
