Last month the club from Ibrox issued a statement claiming that there were underlying issues with the Lanarkshire based official.
Since issuing the statement Collum hasn’t been put in charge of a single match involving the tribute act- increasing the chances of other clubs suffering from Collum’s ‘look-at-me’ style of refereeing.
After 24 minutes a borderline decision resulted in a penalty to Aberdeen which allowed Stevie May to equalise. Soon after, right in front of Collum Niall McGinn flew into a challenge on Ryan Christie that could easily have broken the Celtic platers leg.
Collum’s most outrageous mistake was still to come, in the 83rd minute with Celtic leading 2-1 Graeme Shinnie launched an outrageous dive in the penalty box. True to form Scotland’s leading referee pointed to the penalty spot with Sam Cosgrove levelling the scores.
Three of Collum’s Lanarkshire refereeing colleagues, John Beaton, Bobby Madden and David Roome will be in charge of Saturday’s match at Ibrox.
