Chris Iwelumo scored twice as Wolves saw off Sheffield United in a thrilling game to stay six points clear at the top of the Championship.
Iwelumo fired Wolves in front from a tight angle after a frenetic opening.
Brian Howard appeared to have levelled direct from a corner but the ball was adjudged not to have crossed the line.
Instead, Iwelumo made it 2-0 from Karl Henry's cross and Sylvan Ebanks-Blake smashed home a third goal before Matt Spring replied with a neat finish.
Wolves' win was their seventh in the league on the trot - the second time they have had seven straight wins this season - and the club's best since the the spring of 1987.
Sheffield United assistant manager Sam Ellis on being denied an equaliser:
"It was in - there's no doubt about it. It was over the line. We've seen a replay, and it's over the line.
"At 1-0 that makes it a different game. So as far as we are concerned, luck hasn't gone our way - and that happens.
"We felt we played our part in the game, and it was maybe hesitancy on our part (for the first goal); then maybe it was a decision that was out of our control that sent the game the way it did."
Wolves manager Mick McCarthy:
"It was nice to get the seventh win but it was maybe a bit unexpected here.
"We knew it was going to be a tough game and that was the case.
"It was fast and furious, and a real aerial battle, and while they had chances I thought we defended against it really well.
"It was like the Somme out there with three of them carted off but then at the other end we've had some real quality finishes."
