RANGERS boss Pedro Caixinha is facing an anxious wait over the fitness of both his left-backs ahead of next Saturday’s showdown with Celtic.

Skipper Lee Wallace limped off 12 minutes into Friday night’s draw with Partick Thistle and was replaced by new signing Declan John. But now the on-loan Cardiff defender has revealed he is also carrying a knock and is not certain to start tomorrow’s Betfred Cup tie against the same opponents.

John insists, however, that if he can prove his fitness, he will be able to handle the derby atmosphere. “I have got a bit of a niggle as well so we will just have to wait and see,” said the full-back.

“Seeing Lee go down early, I didn’t expect to get a call so early on. When you are coming off the bench that early in the game, it is still a bit mad and there are things going on. I thought I got there in the end and did pretty well.”
