Kilmarnock are hoping to get to the bottom of Jordan Jones’ fitness issues but the winger will not return for Saturday’s trip to face Ross County.
The Northern Ireland international played one Premier Sports Cup game after re-signing on loan from Wigan but is yet to feature in the cinch Premiership.
Manager Derek McInnes said: “Jordan Jones has been sent for another scan this week just to see what is going on with his thigh, because he had a bit of a setback after training last Thursday.
He will miss out this weekend. “We are still waiting for the outcome on Jeriel Dorsett’s scan. We think it’s some sort of ligament issue.” McInnes will lock horns with old friend and rival Malky Mackay for the first time in 10 years when he takes his team to Dingwall.
