Goals from Alan Browne and Tom Barkhuizen sealed the points for the Lilywhites, with Clayton Donaldson scoring a consolation late on for Wanderers.
Speaking to bwfc.co.uk following the final whistle, manager Phil Parkinson covered the following topics..
On his assessment of the game...
"I thought we started okay, as we had good chances in Josh Magennis' shot and header early on."
"But Preston got control of the game and we were poor today in terms of passing the ball to each other.
"We have done that a lot better in recent games, Sheffield United in particular, but today we didn't do that.
"The goals we conceded were soft. The first goal we got done with a one-two and the second one is a basic mistake.
"If you look at that second goal, it was a period of the game where we were having some pressure and we were doing a lot better.
"We need to do better to show more resiliency and not give away cheap goals."
On conceding just before the break...
"It's always a mood changer when you concede just before the break and it was poor from my point of view."
"We came out in the second half a lot better and the momentum was with us up to the second goal and in fairness, the lads did go out and grab one back.
"There are other games like West Brom where I have come away and thought we've played well and matched our opposition.
"Today, I didn't feel like we did that.
"The disruption we had at the back I think showed as we looked disjointed at times.
"We need to rectify that come Tuesday night."
On Luca Connell's injury...
"First and foremost it was a massive blow for us."
"He is a player with real quality that he has showed in the games he has played so far.
"It was a high octane Lancashire derby - he is a young lad and we believe he has strained his calf."
On nearly getting back into the game late on...
"We have had a real go to get back into the game and I am pleased for Clayton today to get his goal."
"However, we need to play like that throughout the game and if we had done that, we'd have given Preston more problems.
"It is back to the drawing board for us."
On moving past this game and onto Birmingham City...
"We've had our say in the dressing room about what we felt we should have done better today."
"We need to get back to work and get ready to go again."
