Referee chief seeks talks with clubs over ‘DOGSO’ red.

A similar incident involving Rangers’ Mickey Moore being challenged outside the Livingston penalty area by Cammy Kerr in the teams’ 2-2 draw in the Scottish Premiership was also discussed.

Rangers were not awarded a foul but Cullum said an on-field review should have taken place, resulting in a free kick and red card for Kerr. The incident occurred late in the match.

On the same day, Celtic lost 2–1 at home to Hibernian in a match that saw a red card for home player Auston Trusty, which was awarded following a VAR review. Celtic unsuccessfully appealed against the dismissal.

Cullum said it was a “clear red card” for “excessive force” towards his marker Jamie McGrath at the corner.

In the same match, Celtic unsuccessfully claimed a penalty after Warren Ohora’s challenge on Liam Scales. Collome said there should have been an on-field review and a penalty awarded.

Cullum accepted the penalty awarded by VAR for handball against Rangers’ Dougon Sterling in a 2-2 draw with Celtic in the Premier League, against Partick Thistle’s Robbie Crawford in a 2-1 Scottish Cup defeat to St Mirren and against Simon Murray in Dundee’s 2-2 league draw with Dundee United.

Rio Hattat’s penalty was saved for Celtic but he eventually scored in the aftermath, Dan Nlundolo scored St Mirren’s penalty against Thistle and United took the lead through Amar Fateh’s conversion.

Alex Oxlade-Chamberlain has been booked for a challenge on Motherwell’s Elijah Gast during Celtic’s 3-1 home win last weekend.

“We would sometimes describe this as a high-end yellow and orange card,” Collum said.

“I know there are people in refereeing who think this leans more towards a red card.

“Is there something obvious here in the images we see that would bring the referee to the screen to get a red card? I don’t think so.

He added: “But I can also say that if the referee had given the red card on the pitch, we would have completed this decision as well.”
