Celtic hero Charlie Nicholas insists Dundee United's Ryan Edwards should have been red carded for his challenge on Alfredo Morelos at the weekend.

The Colombian striker was forced off the pitch on a stretcher after suffering a nasty gash to his upper thigh following the challenge.

After the game Ibrox boss Steven Gerrard suggested that Morelos would have been sent off if the shoe was on the other foot, but Nicholas believes this comment was irrelevent.

Writing in his Daily Express column, he said: "It should have been an easy red card but the officials got it wrong. 

"I fully expect compliance officer Clare Whyte to look at the incident again and for the SFA to take retrospective action against the Dundee United defender. 

"I don’t think Edwards would have any complaints either. The challenge was poor and it was clear for all to see that Morelos was caught high on the knee. 

"The Colombian was stretchered off with a deep gash and he can count himself fortunate that he didn’t suffer a more serious injury. 

"You could hardly blame Steven Gerrard for coming out and saying Morelos would have been sent off if the roles were reversed. 

"He was defending his player, and rightly so, because it was a bad tackle, but such talk is pretty irrelevant. 

"The reality is that Morelos probably wouldn’t have made a challenge like that. 

"He has never been the sort of player who jumps into tackles. We have never really witnessed that in his character. 

"He is more likely to punch or elbow an opponent when the red mist sets in. You don’t really see Morelos getting caught up in reckless or dangerous challenges. 

"He got sent off for kicking out at Scott McKenna’s head at Aberdeen two years ago, but that was more petulance than anything else. 

"Morelos hasn’t been a particularly vicious player during his time at Ibrox – more stupid and too easy to wind up."
