Kris Boyd is adamant John Beaton called two major decisions badly wrong in booking Alfredo Morelos for diving instead of awarding a penalty and ordering Steven Gerrard to the stand against Livingston.
The furious Rangers gaffer confronted the referee and was picked up by TV cameras swearing and telling the official he was "out of order", presumably over the penalty flashpoint before being shown a red card.
Morelos was sent through on goal and rounded keeper Max Stryjek before he was clearly caught for what looked like a certain penalty.
Instead the striker, who barely complained, was booked by the referee.
And Boyd reckons the official was guilty of a rash decision with the Ibrox boss which he will now regret .
He said of the red card flashpoint: "I think Rangers are so close to winning a league title and emotions are running high.
"Yes, he's had a go but I think John has to realise 'I might have made a mistake here'.
"Emotions are running high and people can be angry.
"You need to be sensible. As soon as John has gone in that tunnel and sat down he will be thinking 'Did I get that right?'
"And when he's been told he's got the wrong decision and he's sent off Steven Gerrard for something he's going to be right with, he had a rush of blood.
"And when he comes back down he will say to himself I've got this totally wrong."
Boyd was also sure that Morelos did not dive and his team should have been awarded a spot-kick.
He told Sky: "There's no doubt it's a penalty. When you go around the goalkeeper and you have an empty net you are not going to go down.
"It's a penalty. It's the last angle you see it from you can see he brings him down.
"Alfredo Morelos is going at top speed, you can see there he's going past him.
"You can see it's a penalty kick. I can't understand why a penalty hasn't been given there."
