Before the match, Preston interim boss Jason Euell said he was looking to put “things right” after a run of six defeats in seven games, and he got an instant response from his players.
When the QPR defence were caught napping, Kenny powered his way towards goal, and with only Charles to beat he fired into the bottom left corner from close range.
Looking for a quick equaliser, QPR dominated possession but wasted a string of opportunities with Cirkin having an effort blocked, before Jonathan Varane headed over minutes later.
That proved to be the end of Cirkin’s positive involvement, with the defender promptly shown a straight red card for a dangerous late tackle on Leo Leroy.
Pounding on a loose ball in the QPR box, Kenny then got his second. The striker had no difficulty in turning his defender before lashing the ball into the net to the delight of the travelling supporters.
