Wolves goalkeeper Wayne Hennessey has been ruled out for the remainder of the season in a blow to the club's slim survival hopes.
Hennessey injured his knee in the weekend stalemate with Sunderland and scans have revealed a torn cruciate ligament.
The Wales international had made 58 successive Premier League starts since regaining his place midway through last season.
Dorus de Vries, signed last summer from Swansea, is now poised to make his league debut in Sunday's crunch home clash with title-chasing Manchester City.
Wolves are eight points from safety with four games to go.
