RANGERS will assess midfielder Ryan Jack today ahead of the second Old Firm clash of the campaign.

The 25-year-old was stretchered off in the first half of the 2-0 win over Motherwell last night and is a major doubt for the trip to Parkhead this weekend.

Jack was caught by Well defender Cedric Kipre and was in clear discomfort as he was replaced by Jamie Barjonas a couple of minutes before the break.

Striker Eduardo Herrera also had to receive treatment after Kipre caught him in the face with a boot but he was able to continue for the remainder of the game.

Goals from Danny Wilson and Alfredo Morelos clinched all three points for Graeme Murty’s side but the Ibrox boss now faces another injury headache ahead of the Celtic showdown.

Murty said: “He is in a bit of pain and a bit of discomfort. He’s in a brace at the moment and we will assess him [today].

“Looking at the manner of the injury and his departure from the pitch he would be a doubt for Saturday.

“But, he’s a hardy guy and if there is any chance of him being involved he will be desperate to try and make the team.

“I’m going to plead ignorance when it comes to the challenge and say I was following the line of the ball.

“I’m sure I will be getting sent loads of different clips from different angles but now I’m more concerned with the player than anything else.”

Rangers went into the Well fixture on the back of successive Premiership defeats to St Johnstone and Kilmarnock as they have fallen to third spot in the standings.

But the Light Blues avoided a hat-trick of league losses as Wilson and Morelos netted after the break to ensure they got back to winning ways.

Now attentions will turn to the Old Firm fixture as Rangers look to round off the year on a high note against Brendan Rodgers’ side.

Murty said: “It gives me hope that the guys can stand up to the challenge, they stood up to really physical challenge against Motherwell.

“We have a different challenge on Saturday, it’ll be a technical and tactical one. We need to show a mentality and desire to represent the shirt and hopefully we can make the fans proud.

“If we show that mentality and desire then who knows what can happen.

“We stood up to Motherwell and we knew what was coming and there wasn’t any petulance from us.

“We stood up that challenge and whatever they through at us and came out of it with a good result but we need to have mentality and desire to step up and I thought we did that.”
