John Halls told the Official Web-Site: "My back is playing up again, which is very frustrating. Playing against Arsenal recently didn't help me really but I've got to get on with it now and hopefully get back as quickly as possible.
"It hasn't got any worse but it's certainly no better. I don't think I'll make it for the Leeds game which is disappointing because they aren't doing so well just now and hopefully with a good crowd here we can turn them over."
