Rangers interim manager Graeme Murty has confirmed that striker Kenny Miller faces a "significant amount of time out" after suffering a ruptured hamstring.
The 37-year-old had to be replaced 15 minutes into his side's 2-1 win over Hibernian at Easter Road last Wednesday after going down clutching his leg.
Gers had hoped that Miller, who had been an ever-present in the team since the departure of Pedro Caixinha in October, would make a swift recovery.
Murty, however, revealed that further scans showed the full extent of the problem.
"Kenny's is going to be more significant than we thought. Unfortunately it looks as though he has a rupture of his hamstring, so he is going to have a significant amount of time out," the caretaker boss told the official Gers site.
"We were hopeful given the way he presented, and given the fact his range was okay, but once we've scanned it, we have seen there is significant damage in there, so we have to be more conservative in our approach with him.
"That's a painful one for him and a sore one for the group as he is an integral part of everything that we do around the place. If anyone knows Kenny, they know the standards that he drives. So we are going to miss him."
Miller, who signed a one-year contract extension last season, has made 18 appearances this season, scoring four goals.
