Wolverhampton Wanderers' relegation woes have deepened following a 2-1 defeat at Stoke City.
The hosts should have been ahead early on, but Jonathan Walters could only direct his header at Wayne Hennessey after Peter Crouch had headed across goal.
The Premier League strugglers took a lead in unusual circumstances on 26 minutes when Michael Kightly's attempted pass missed everyone, including Stoke goalkeeper Asmir Begovic, to find the net.
It took the Potters 20 minutes to draw themselves level as Robert Huth volleyed in after Wolves had failed to clear a free kick.
Walters could have put his side ahead at half time, but again he headed straight at Hennessey.
Despite a spirited start to the second half from Wolves, they fell behind on the hour when Crouch nodded in Jermaine Pennant's free kick.
A sixth consecutive defeat for Wolves means that Terry Connor's side stay six points adrift of safety.
