Aston Villa boss Alex McLeish has confirmed that Charles N'Zogbia is facing a month out of action with a knee injury, while Alan Hutton has been sidelined with a calf problem.
• McLeish denies N'Zogbia rift
N'Zogbia, 25, is to see a specialist in his native France to try and assess the extent of the setback suffered in a training ground collision with midfielder Gary Gardner last week.
It adds to an already lengthy injury list with full-back Hutton now also on the sidelines with a calf injury, while Darren Bent, Richard Dunne and Ciaran Clark are long-term absentees.
"Charles is going to get specialist attention in Paris," MCLeish said We've just got to see if his knee ligament is going to take much longer (to heal).
"But we think it's a medial knee ligament problem, maybe three or four weeks out. It happened in a training ground collision with Gary Gardner. They banged knees together and Charles kind of opened his knee up a little bit.''
Hutton is facing at least two weeks out of action and will miss the next two games with Chelsea and Liverpool with the setback sustained in the 3-0 defeat at Arsenal on Saturday.
McLeish said: "Alan Hutton came off with a calf injury against Arsenal and he could be out for two or three weeks. He'll need a scan.''
