Rangers will be without Leon Balogun for their Scottish Cup clash with Celtic next weekend.
And James Tavernier is also unlikely to be fit for the Ibrox tie as he continues his recovery from a knee injury suffered in February.
The Rangers skipper hasn't played since the 4-3 win over Antwerp in the first leg of the Europa League round of 16, but it had been hoped he would be fit to face Celtic.
Steven Gerrard has revealed he's still a major doubt, despite some 'good' days of training towards the end of last week.
Balogun suffered a calf and achilles injury on Saturday in training and it forced him out of Sunday's game against Hibs at Ibrox.
Ryan Jack is also still waiting on results of his scan on his calf issues that have kept him out since February 21 as well.
Gerrard said: "James has again had a good couple of days since we last spoke and he's pushing hard to be involved at the weekend. We'll only do that if he is ready, we won't force that. He's been out too long for us to force that.
"He'll have to show this week that there's more progression and get him out amongst the team at some point if he's to earn a place in the squad.'
"Unfortunately, Leon is going to be out. He felt a calf/Achilles area yesterday morning and left the training session.
"Until we get the scan result we won't be able to know the outcome of that. But he's limping about, which tells you he has obviously little chance of making next weekend."
