Barry Ferguson and Aiden McGeady in agreement over what Jim Gillespie did at Rangers
Rangers were not too happy with Mika Baur's challenge on Ryan Naderi in last week's Old Firm win over Celtic.
The Gers were comprehensive 3-0 winners over Celtic in the Scottish League Cup quarter-finals at Ibrox.
Dan Neil scored twice for Derek McInnes' side, with Kevin Kelsy's first Rangers goal sandwiching those efforts.
But Rangers forward Naderi is a doubt for the second in an Old Firm double header in the Scottish Premiership at Celtic Park this Sunday.
McInnes described Naderi's ankle as a "mess" after the second-half incident, which saw Celtic awarded a free-kick.
That led to chief executive Jim Gillespie making his thoughts on the matter clear.
What did Jim Gillespie do after Ryan Naderi incident at Rangers?
Rangers are already short in the forward department at the moment.
Youssef Chermiti is sidelined for the long-term with a serious knee injury, while captain Lawrence Shankland is out for months with a hamstring injury.
If Naderi is out as well, then McInnes only has new boy Kelsy, and Bojan Miovski to select from in the striker role.
Previewing the clash at Celtic Park on Sunday, McInnes was asked about the Naderi challenge and if he had sought an explanation.
McInnes stated that he himself has not, but that Gillespie has been in contact with Scottish refs chief Willie Collum.
"The club, Jim Gillespie, spoke to Willie Collum and the SFA about it. I'm really not happy with the challenge, but I'm not going to get caught up in referee chat," McInnes said.
"I'm surprised that the referee wasn't asked to look at that. I find it strange that it wasn't. Ryan's ankle's a mess. It was a mess, it was a poor challenge."
Ferguson and McGeady agree on Naderi incident
The incident, and Gillespie's consequent chat with the relevant authorities, was a topic of discussion on the Go Radio Football Show.
Former Rangers captain and ex-interim manager Barry Ferguson was reticent to lay too much blame at the door of Baur.
Ferguson stated that such incidents are part of the game, and that he was reluctant to talk too much about challenges in the match.
He said: "I just think sometimes it happens in football, sometimes there is late challenges, some are worse than others.
"I don't like to hear that he's injured, of course, but he is a doubt. I would just speak about what happened rather than speak about tackles."
Former Celtic winger McGeady was in agreement, and questioned whether there was a need to escalate things.
McGeady opined: "I don't know, there's a lot of things that have happened already this season that you can't quite understand why VAR's ruled this way or why the referee's thought that.
"It was just one those instances I think, where you slow it down it probably doesn't look great.
"But again to then appeal and then look for retrospective action, these things happen. I don't think Derek should be, and like he said I'm not gonna be bogged down about referee chat, but he kind of did."
