Pundit Michael Stewart insists Rangers were lucky to be playing against 10-man Aberdeen as he slammed the decision to send off Ryan Hedges.
The Welshman clipped the heel of Alfredo Morelos after letting the striker get goalside, receiving his marching orders as well as conceding a penalty.
The contact was accidental but under the IFAB laws of the game only an attempt to play the ball sees a red card reprieve when the offence is denying a goalscoring opportunity.
Aberdeen boss Derek McInnes revealed that John Beaton had explained the decision, explaining he had no choice but to send off the 24-year-old.
But Stewart insists Hedges should only have been cautioned as he shrugged off a letter of the law interpretation.
Speaking on Sportscene, he said: "I don't think it is a red card.
"We can debate all day long but I would suggest there is enough space within the rules for it not to be.
"It says that if you attempt to challenge and win the ball but you give away a foul you'll be yellow carded.
"All the other offences - e.g holding, pulling or pushing - none of them are (yellow cards).
"So my problem is the rule was changed a few years ago to create a fairness so there wasn't a triple whammy: you get a penalty against you, you get a red card and you get suspended.
"So there's a fairness if you attempt to win the ball.
"I would suggest that incident actually isn't covered within the law at the moment.
"He didn't try to challenge, so if you change it over and you say, 'if you deliberately foul the player, hold, pull or push, you'll be red carded' then all other incidents would be a cautionable offence.
"That covers everything, whereas I would suggest that the law at the moment doesn't cover that incident which is where I think common sense should come into it.
"I don't think any fair-minded football supporter looks at that and thinks that's fair for Ryan Hedges to be sent off."
The other big incident was a potential red card for Curtis Main and while Stewart thinks the striker was lucky he backed Beaton's decision.
He said: "He's lucky not to get a red when you watch that at full speed.
"From where the referee and the linesman are it looks very, very bad.
"But when you see the final angle, for me there isn't enough contact.
"He barely touches Barisic when it's up high.
"He's very lucky that he didn't get red carded because I think in real time it looks very, very bad.
"But I think the yellow card is the right decision."
