What is the team news?
Rangers defender Lee Hodson is a doubt for the final Old Firm clash of the season on Saturday.
Reports on Thursday suggested the Northern Irishman could miss the Ladbrokes Premiership showdown after a training ground tumble left him on crutches. Manager Pedro Caixinha, however, would only say his situation was being assessed ahead of the Ibrox fixture.
Meanwhile, Lee Wallace (stomach), Rob Kiernan (calf) and Philippe Senderos (knee) are all still missing along with long-term casualties Jordan Rossiter (calf) and Niko Kranjcar (knee).
Provisional squad: Foderingham, Tavernier, Bates, D Wilson, Hill, Beerman, Toral, Hyndman, Holt, Waghorn, McKay, Garner, Miller, Halliday, Dodoo, Windass, A Wilson, Forrester, Hodson, Alnwick.
Celtic skipper Scott Brown is free to face Rangers in Saturday's Ladbrokes Premiership clash at Ibrox after his recent red card against Ross County was downgraded to yellow on appeal.
Brown's caution took him over the disciplinary threshold again, however, and he will miss the following two matches against St Johnstone and Aberdeen.
Striker Moussa Dembele will miss the Ibrox match with a hamstring injury picked up in the 2-0 William Hill Scottish Cup win over the Light Blues at Hampden Park on Sunday.
Provisional squad: Gordon, Lustig, Tierney, Gamboa, Izaguirre, Toure, Boyata, Sviatchenko, Simunovic, Forrest, Sinclair, Armstrong, Brown, Bitton, Roberts, McGregor, Griffiths, Mackay-Steven, Kouassi, Aitchison, Bailly.
What are they saying?
Rangers' Martyn Waghorn
Asked if beating Rodgers' men was starting to feel like an impossible task, the Englishman said: "If you think like that it will become that. It will be in the back of your mind the whole time.
"The thing about this team is that we have a lot of big personalities, a lot of big characters.
"We're all disappointed from the weekend but we can use that the right way.
"We're going into Saturday in front of 50,000 at Ibrox, it's the last Old Firm of the season and we've got a point to prove. It's set up to be, hopefully, a good game.
"I understand we've not won against Celtic yet this season.
"But there is always going to be a time and there is always going to be someone who is going to beat them and you have to be positive going into these big games."
Celtic manager Brendan Rodgers
"It is their home game and they will look to maybe press the game a little bit more.
"But it is always difficult and if they do decide to press more then it can be even better for us.
"It will open up the space behind the pressing line, a big space and we have got speed in our team.
"But we will prepare as we normally do for a tough game. We played very, very well on Sunday.
"The only disappointment was the scoreline didn't really reflect the dominance of the game.
"We will respect the opponent which we always do but really look to impose our style on our game as we have done all season."
What are the odds?
Rangers win - 15/4
