Blades waiting on Harper prognosis

The former Reading man has missed the last two matches with the problem and will see a specialist on Thursday night for further assessment. Assistant manager Sam Ellis admits the club are in the dark as to the seriousness of the injury and is hoping Harper is not sidelined for a lengthy spell. "He is with out physio Paul Teather and seeing a specialist. After that we will evaluate it," Ellis told the club's official website. "It is one of those tricky ones that could see him out for the season or just a day or two, we don't know, and that's why we need to have a look at it. "He will be a miss, for sure, because we feel that he has been improving all season and we had got him to the point where he was hitting his best form - that is the really frustrating part."
