QPR manager Neil Warnock admitted the dismissal of defender Damion Stewart cost his side in the 1-0 defeat at Reading.
Warnock lost his unbeaten start to life in charge of the Hoops when Gylfi Sigurdsson blasted in an 85th-minute penalty but had seen his side boss the game until Stewart's 45th-minute red card.
The centre-half had already been booked for a high challenge on Shane Long before stupidly challenging goalkeeper Adam Federici as he made a clearance.
"You don't always get what you deserve in football but we were the better side with 11 men," said Warnock. "You don't often come to Reading and out-play them but we did and I have learned a lot about the players. You can say that the red card cost us.
"We defended really well. Damion's first booking is never a booking in a million years. He never took his eye off the ball.
"But the second one was his own fault. What was the goalkeeper going to do other than kick the ball? He must have launched 100 kicks so it was silly and he let his mates down."
