James McFadden reckons James Tavernier could have seen red for Rangers against St Johnstone.
The Ibrox skipper appeared to catch Ali Crawford with a late tackle on the ankle in the second half with whistler Willie Collum awarding a free-kick.
However, no further punishment for the lunge was issued, but Crawford would limp off the park moments later in the 1-0 defeat in Perth.
The incident was brought up by the Sky Sports pundits after the full-time whistle, with McFadden pointing to the rule book.
When asked about the tackle, former Rangers favourite Kris Boyd stated: "I think it's a yellow card. A yellow card would be for (it being) reckless, but I don't think ti's excessive force."
McFadden, however, felt that the follow through merited a more serious punishment, arguing: "I think he follows through there. The more I see it, I don't think he needs to extend his leg."
Boyd clapped back: "I think when you slow anything down it looks worse. Again, maybe if we get VAR the referee has a decision to make."
St Johnstone star David Wotherspoon, who joined the panel, added: "There is follow through and there is a straight leg there.
"It looks a nasty one for Ali but hopefully he is alright because we need as many players fit as possible, obviously going through a bad spell with injuries.
"We want everyone fit and ready to go."
