The result leaves Preston heading into the weekend in 16th place in the table, and on track for a lower mid-table finish with just nine matches of the season left to play.
Speaking after the game, Lilywhites boss Alex Neil revealed: "That was the first time I have lost to a Neil Warnock team – that’s really frustrating.
“We are tailor-made to play against that type of team because they want to lock you on. The long and short movements to work against that are what we do all the time. We’d started really well and the referee has denied us the opportunity to get points which are crucial to us.
“The most annoying thing about it for me was that when I went over to see the referee I decided to be overly pleasant so that I didn’t get in trouble.”
Next up, Preston host Luton Town at Deepdale on Saturday afternoon, and a victory for the Lilywhites could see them leapfrog the Hatters into 14th place, if results elsewhere also go their way.
