Newcastle took a huge step towards Premier League survival as Chris Wood's penalty proved enough to beat a blunt Wolves side at St James' Park.
The January signing slammed home the second-half winner at the Gallowgate End after being fouled by Wolves keeper Jose Sa at the end of a flowing team move.
VAR checked if Sa had made adequate contact, after an earlier review had denied Wood in the first half, when he saw a goal chalked off because team-mate Bruno Guimaraes was narrowly offside in the build-up.
Wolves failed to touch the ball in the Newcastle area in a dire opening 45 minutes and manager Bruno Lage will wonder why it took until the 80th minute for his side to work home keeper Martin Dubravka when Fabio Silva forced a diving save.
