Speaking to the Official Club Website, Town boss Joe Royle said that he was glad that they had at last found the root of the problem that has haunted the former Sunderland player since he last played a first team game in August.
"It's good news in one way for Chris in that the surgeon has found a small tear in a cartilage in the hip joint," He confirmed
"It went undetected in the previous scans and operation so at least we know the reason behind the problems Chris has been having this season. Unfortunately, the downside is that he will miss the rest of the season."
