Birmingham City manager Lee Clark has revealed that Stephen Carr looks likely to miss the majority of the season after he underwent knee surgery.

Carr suffered a thigh problem in pre-season after beginning his comeback from an injury picked up in January, but a scan revealed that he required an operation on his knee and Clark has admitted that it is a huge blow for the club.

Clark told BBC WM: It's a massive blow for him as he's worked ever so hard to get back - and for me.

"He's had ongoing problems with his knee, with a cartilage problem, then, just when he was on the verge of making a comeback, he picked up a thigh strain against Antwerp. When they opened him up, they found quite a bit of damage.

"He's now had surgery, which will keep him out for a minimum of six months."

Carr has made 121 appearances for Birmingham City since coming out of retirement to play for the club in 2009.
