Aston Villa defender Luke Young is set to miss the next three matches with a torn hamstring.
Young missed last weekend's goalless draw with Chelsea after suffering the setback in training the previous day.
But scans have revealed the injury is worse than first feared and Villa boss Gerard Houllier is resigned to being without the firmer England full-back for at least a fortnight.
That means Young is likely to miss Saturday's clash at Sunderland, the Carling Cup meeting with Burnley on Wednesday and the home derby with Birmingham on October 31.
Houllier confirmed: "The doctor has told me Luke will need at least another two weeks (to recover) because it is a minor tear.
"It's a blow because it's worse than we initially thought."
