Aston Villa boss Unai Emery admits Ezri Konsa will be missing for four weeks.
The defender is recovering from a knee injury.
However, fellow stopper Pau Torres is fit for the FA Cup replay against Chelsea.
Emery said: "He is injured. He has a knee sprain and he is going to be not available for three or four weeks more or less.
"The other players are out for tomorrow. Lucas Digne is progressing well but is out. Pau Torres has trained with the group and he will be on the bench."
