Aston Villa boss Alex McLeish admits mounting injuries are worrying him in their relegation fight.
Charles N'Zogbia is now out for a month.
McLeish said: "He's going to get specialist attention in Paris.
"We've just got to see if his knee ligament is going to take much longer.
"It was a collision with Gary Gardner in training. They banged knees and Charles kind of opened his knee up a bit.
"James Collins signalled that his hamstring was tight. We will have to wait and see."
