Celtic left-back Greg Taylor faces at least two weeks out with a hamstring injury.

The Scotland international went off in the first half of Celtic’s 2-2 draw with Rangers on Monday after aggravating a problem he had experienced in his previous match.

Ahead of Saturday’s cinch Premiership contest with Kilmarnock, Celtic manager Ange Postecoglou said: "Greg [Taylor] has got a slight hamstring injury and he'll have a scan. It's not too serious but he will definitely miss a couple of weeks.

"He's the only one out from the game. In terms of the ones returning, they are all closer but none of them are available for tomorrow. It's really just Greg out."

The Australian also made clear that he was not happy with some of the decisions made by referee John Beaton in the recent derby.

Postecoglou highlighted Connor Goldson's handball incident as one in which he feels the officials did not get the decision right,

"It's a penalty," he continued. "I have seen people do all sorts of mental gymnastics to show why it is not a penalty which suggests that it is, so stop trying to find a reason it's not.

"If it wasn't there would be a simple explanation for that. It is one of things which it is not just confined to us as a club, as other clubs are in the same boat.

"It is just really confusing for players in the box to know what they can and can't do. It seems it changes depending on who's in charge of the decision-making process.

"There has been zero consistency in the decisions being made. My view on this and it has always been the same in 25 years of coaching and managing I have always abided by the referee's decision.

"You would be hard pushed to find me criticising any referee in my whole tenure as a manager.

"I have always believed that these things even themselves out. They are human beings, they make mistakes, we make mistakes, players make mistakes, over the course of the season these things usually even themselves out.

"When I look at the introduction of VAR and the decisions that have gone against us, in particular, then there is zero chance that is going to even up between now and the end of the year because it is remarkable that we have had at least three major decisions go against us.

"Again we can just say it comes down to interpretation or whatever people want to say but I guarantee you that if that game finished 2-2 and it was Rangers that were denied that decision, then the talk this week would be about how that was a title-defining decision.

"It's always been a penalty. There were two saves made in the game, one by Joe Hart and the other by Connor Goldson. That was it."
