Rangers are facing an injury sweat over Oscar Cortes after he limped off against Kilmarnock.

The winger - signed in January - was replaced by Scott Wright after 70 minutes.

And it appeared Cortes was holding his hamstring as he hobbled off the park after receiving treatment.

The 20-year-old was unable to continue after receiving medical attention in a blow to Philippe Clement's side.

Cortes has already played seven times for Rangers since his move to Scotland from Lens last month.

And the winger already has a goal and two assists to his name for Rangers having quickly become an important player for Clement.
