Michael Stewart believes the penalty awarded to Rangers at Easter Road last night shouldn't have been given.

Dujon Sterling went over in the box under the close attention of Hibernian defender Jordan Obita. Referee Steven McLean didn't hesitate as he pointed to the spot.

James Tavernier's spot kick was saved by David Marshall, but John Lundstram was alert to the follow-up, as he bundled the ball over the line to give the visitors the lead. 

Fabio Silva would add to Rangers tally in the second half, as Philippe Clement's side booked their slot in the last four of the Scottish Cup.

On the subject of the source of Rangers' opener though, Stewart disagreed with the decision. 

On co-commentary duties, the one-time Hibs player said on Viaplay:  "I'm not sure he clips him, it's just clumsy and he falls on the back of him. But is it a case that Sterling just feels the contact and goes over?

"It's a difficult one. I don't think that's a penalty. I think Sterling feels a bit of contact and goes over. I don't think there's any clipping of the heels. I don't think Obita impedes him. I think there is a coming together, that is going to happen in football.

"But as soon as Sterling feels any contact, he's gone to ground there. Personally, I don't think that's a penalty kick.

"At times when you see clashes like that there can be a clip of the heels and somebody sends somebody else down. I don't think that happened on that occasion."

He added: "Had he not given the penalty kick it might have just been play on, VAR might bot have got involved. I think when you see the incident as a whole, Sterling is goal side of Obita and he goes down. Instinctively you think foul, penalty kick.

"But when you're looking at it and trying to see 'has he kicked him, has he clipped him, has he impeded him?' There's a bit of contact but I don't think that's enough that's a penalty.

"Many, many others Im sure would disagree but I think it's very, very similar to the foul, or the non-foul, that was down in front of us with Martin Boyle and Diomande in the build-up to that."
