KENNY MILLER reckons the rules regarding clubs being unable to appeal yellow cards should be looked at as he defended Rangers team-mate Andy Halliday for his sending off against Morton.

The midfielder was given a second booking by referee Barry Cook in the aftermath of Barrie McKay's strike that clinched a 2-0 win for Mark Warburton’s side at Cappielow.

Already on a caution for a foul on Declan McManus, Halliday was deemed to have made an ‘offensive gesture’ towards the Ton support from the middle of the park.

He will now miss the Championship clash with Falkirk this weekend and Rangers have no avenue of appeal because it was not a straight red card offence.

And Miller, who opened the scoring with his 12th goal of the campaign, said: "After seeing it, I think there's a lot of sympathy. When he first got sent off, I was angry because I thought ‘why has he given the ref an opportunity to send him off?’, but when you see it again there's no offensive gesture, there's no running towards opposition fans, so he's going to be a loss.

“But we've got a big, good squad and it's an opportunity for someone else to come in now.

"The rule could definitely be looked at. Whether it is right or wrong and only the ref will know that.

“Gesturing - and I don't even think there was any gesture towards the opposition fans - I think sometimes common sense should prevail and there should be a case of looking at it if it is two yellow cards. But we'll move on and focus on Falkirk.

"He's celebrating a goal. He might be looking over his shoulder, it's not as if he is looking over his shoulder to incite them or anything.

“It's a very harsh booking. There's no offensive gesture there.

“You've seen it many a time when players score and they've given it the ‘sssshhhhh’ sign - now that's a gesture. But there's none of that and it's very harsh.

“Sometimes you get carried away and do things you shouldn't, but in Andy's case he's done nothing wrong and he's not caused any problems. It’s a poor yellow."
