QPR boss Jimmy Floyd Hasselbaink was furious that Preston’s Tom Clarke was not sent off before the home side eventually equalised in the 1-1 draw at Deepdale.
Sebastian Polter’s early goal looked like being enough to give improving Rangers a third consecutive victory.
But the tide turned against them late in the game, with Clarke somehow escaping with just a yellow card after pulling back Tjaronn Chery before Eoin Doyle headed in an injury-time goal.
“The rule book says what it says, so I don’t understand why that is a yellow card,” Hasselbaink said.
“It’s a proper pull-back of the shirt. He (Clarke) was the last man and he (Chery) is going through one-v-one to the goal.”
Doyle’s goal came after Preston had struggled to create chances, while Rangers were dangerous on the counter-attack and had a number of opportunities to add to their lead.
“We should have got the three points. They put pressure on us but we soaked it up,” Hasselbaink added.
“I must say in the second half we played really well and passed the ball. Preston became more desperate and I didn’t see them scoring.”
