Reds boss Billy Davies said: "He's picked up a slight ankle injury but it's not quite as serious as we first thought it would be. We thought it was more of an Achilles problem but thankfully it's not.
"He is set for a scan and fingers crossed it won't be too bad.
"But that's what happens when you are coming back from a long time out, you pick up other niggling injuries. It's been the same with Julian Bennett."
