Jimmy Floyd Hasselbaink said an unfair first-half yellow card affected Karl Henry’s performance in QPR’s 1-1 draw at Bolton.
Henry was substituted in the second half by boss Hasselbaink, who insisted the midfielder should not have been booked for a 21st-minute challenge on Darren Pratley.
Hasselbaink said: “The referee didn’t help, giving one of our players a yellow card when it was a beautiful 50-50.
“It was an honest 50-50 that my player won and that is what football is about.
“Of course (after the booking) you have to be careful and you can’t play how you really want to play. For him it was (then) a bit on the back foot.”
The result moved Rangers up to 12th in the Championship table but they have won just two of their 14 matches since Hasselbaink took over as manager.
They salvaged a point at the Macron Stadium, where Matt Phillips netted an injury-time equaliser – his seventh goal of the season.
“The reaction of the players after the (Bolton) goal was good,” Hasselbaink said.
“We knew they were going to be direct at times, and we adjusted well. You have to be stubborn and we did that.”
