Former Coventry CIty forward Marlon King is out for the rest of the season.
The Birmingham City player underwent surgery on a knee injury on Monday which will keep him out of action until pre-season.
Blues boss Lee Clark told the Birmingham Mail; "Marlon will be out for the season.
"He went in to see what they could find as there is obviously an issue with his knee as it keeps swelling up.
"They’ll do a clean up and then we’ll rehab him in terms of getting him ready for pre-season."
