Philippe Clement revealed a specialist is looking into Oscar Cortes’ muscle injury, with no time frame yet for the Rangers winger’s return.
The 20-year-old Colombia international hit the ground running after joining the Light Blues on loan from Lens last month, with the Govan club having an option to buy in the summer.
Cortes scored his first goal for Rangers in the 5-0 thumping of Hearts at Ibrox last weekend but had to come off during the 2-1 win over Kilmarnock at Rugby Park on Wednesday night which kept the Light Blues two points clear of Celtic at the top of the cinch Premiership.
The Belgian boss confirmed striker Kemar Roofe and midfielder Ryan Jack would return to the squad for the home game against Motherwell on Saturday, but on Cortes he said: “Oscar will be out, I don’t know how long.
“We are looking into that with the doctor and specialist.
“It is a muscle injury, but I cannot say much more at the moment.
“I don’t want to speak about a half-empty glass.
“I am focused now on the players who are available for this game, because otherwise I would have lost a lot of energy in the last couple of months and that is useless.
“It is a pity for him and the team, yes, it is an opportunity for another player to show it and to do it, it works like that.”
