Birmingham City midfielder Craig Gardner is battling to be fit for the upcoming Carling Cup quarter-final derby clash with his former club Aston Villa.

Gardner, who is Blues' leading scorer with four goals this season, missed Saturday's shock 1-0 home success over Chelsea with an ankle injury.

Blues boss Alex McLeish is guarded about Gardner's chances of being fit to face Villa on December 1 at St Andrew's.

He said: "We are still awaiting the results coming from the specialist in London.

"We thought it (the ankle) might be worse than it actually is.

"We are hopeful Craig is only going to be out for two to three weeks so we will await the specialist report.

"Is he out of the derby? I don't know, I need to check with the doctor."

Gardner moved across the city to Birmingham in January and helped the club he supported as a boy to a goalless draw at Villa Park last month.

His replacement, Lee Bowyer, scored the winner against Chelsea - his first goal for 11 months.
