Philippe Clement insists Rangers need to “find solutions” as he is handed another injury blow.
James Tavernier is set to be on the sidelines for “a few weeks” after picking up an injury at the end of their 2-2 draw away to Motherwell on Sunday.
Rangers welcome Celtic to Ibrox on Thursday as they attempt to close the 14 point gap Brendan Rodgers’ side have put between themselves and their rivals at the top of the Premiership table.
But now the Rangers boss has to deal with the absence of his captain and right-back.
“Nobody will come back into the squad and we lose Tav also, who got an injury at the end of the game,” he said.
“We took a scan, and there’s clear damage there so he will be out for a few weeks.
“We always take risks, and you have to do that in this business, but no crazy risks, that players can be out for months.
“It’s a blow and every injury is a blow, and we have had a few blows in that way the last weeks, the last months, first with Nana [Neraysho Kasanwirjo], then with John [Souttar], then with Leon Balogun, with Ridvan Yilmaz before in defence and with Tav now.
“But it’s about finding solutions and looking for solutions and go and work out of that.
“In these last two games every time that they have had a shot on goal, it’s almost a goal. Those are the things that sometimes happen in football but normally not two games in a row, but it’s been the case, and we have been chasing games because of that.
“So we need to find solutions now.”
