Rangers midfielder Ryan Jack faces a race against time to be fit for the first Old Firm match of the season at Celtic Park.
The influential midfielder pulled up with a calf issue in the 4-0 win over Dundee United at Ibrox and Rangers boss Steven Gerrard admitted he could be up to four weeks on the side-lines.
With Rangers set to travel to Celtic Park on the 17th of October Jacko faces a nervous wait to see if he will be fit enough to play in the crunch tie as Gerrard also gave an update on Brandon Barker.
“Jacko will be missing for a few weeks at least,” said Gerrard [Rangers].
“I think with him we have to take it day by day but we’ve had confirmation that he has a calf problem.
“So he’ll certainly be missing in the short term. It’s difficult to say whether it will be two, three or four weeks at the moment. But he’ll certainly miss a couple of weeks.
“Brandon Barker is similar in terms of his scan. It’s obviously a different muscle, in the hamstring.
“He’ll be missing in the short-term as well.”
The news will come as a big blow to Rangers and Jack with the Scotland international midfielder a big part of the Ibrox team and usually one of the first names on the team sheet.
Rangers will now need to navigate the Europa League qualifiers without the midfielder who could miss Scotland’s UEFA Nations League playoff tie against Israel as well.
Defender Leon Balogun – who pulled out in the warm-up to the Dundee United game – has also been removed from the Rangers squad to play Lincoln Red Imps.
But the club have been boosted by the return of star striker Alfredo Morelos, who has recovered from a nasty gash on his leg and is fit to play in Gibraltar.
