Conor Coady clinched a welcome away win for Huddersfield Town with a sweet 81st-minute strike.
The midfielder looked like he was about to cross from Nahki Wells' cut-back, but instead sent in a curling ball which beat keeper Scott Carson's stretch and hit the top right-hand corner of the net.
It was Town's first away win since Wolves were beaten in October and their first victory in four visits to the DW Stadium.
The major talking point pre-match was the appearance of Town striker James Vaughan after he picked up a facial injury at Middlesbrough the previous week.
The club had feared a lengthy lay-off, but after getting the green light from a specialist, he played wearing a protective mask.

It was frontline partner Nahki Wells who was to the fore, however, with one shot saved by Scott Carson and a header cleared off the line by Liam Ridgewell.
Town skipper Mark Hudson also had a goalbound header blocked by Andrew Taylor, while home midfielder Chris McCann was denied by Alex Smithies.
Wigan's James McClean volleyed over while both McLean and James Perch has shots blocked as the ball pinged around the Town penalty area.
The second half followed a similar pattern to the first, with neither side able to take full control.
Wells shot wide and fluffed a decent opportunity inside the penalty area before Coady hit the winner.
