McGreal this week saw a specialist and was told that he will require an injection in the back to try and cure his persistant injury problems that have seen him miss all of this season so far and half of last season.
Speaking to the Official Club Website, Physio Dave Williams confirmed: "John will have the injection and then will be given a plan to follow over the next four to six weeks. We need to get to the cause of the back problem and this is the next step forward."
