The England international centre-back was sidelined for more than a month after injuring the ankle in the FA Cup 3rd round tie against Blackburn Rovers at St. Andrews at the beginning of January.
He returned to the side for the home game against Everton earlier this month but appears to have aggravated the injury in last weekends FA Cup 5th round tie at Sunderland and is considered doubtful for the short trip to Villa Park on Sunday.
