Preston fought back from behind to claim a thrilling victory at Wycombe.
Neil Mellor put Preston ahead with a close-range finish and then set up Iain Hume, who drilled home a second.
Wycombe came back as Gareth Ainsworth's tap-in made it 2-1 and Scott Donnelly's penalty, following Conor McLaughlin's foul on Kadeem Harris, levelled it.
Stuart Beavon headed in Donnelly's corner to put Wycombe in front but Hume equalised with a composed finish before Mellor steered in a dramatic winner.
VIEW FROM THE DRESSING ROOM
Wycombe manager Gary Waddock told BBC Three Counties Radio:
"I'm very pleased and proud of the performance, but frustrated that we've not got anything from the game.
"In many ways we made our own downfall, we needed to defend better, especially when we had the ball in their half of the pitch or when they catch us on the counter attack.
"We've had a few chances to put the game further away from Preston, didn't take them and got punished."
