QPR manager Harry Redknapp was unhappy with his side's defending as they failed to end their home Premier League campaign with a victory after losing 2-1 to Newcastle.
Relegated Rangers started brightly and took the lead through Loic Remy's 11th-minute penalty, but Jose Bosingwa handed the Magpies a route back into the game when he pulled Hatem Ben Arfa's shirt to concede another spot-kick, which the Frenchman converted.
Bosingwa's mix-up with goalkeeper Rob Green then gifted Yoan Gouffran's Newcastle's second goal and the full-back failed to emerge for the second half.
"They were horrendous goals, both of them," said Redknapp.
"I thought it was a poor penalty and once we conceded the penalty we conceded another bad goal.
"It (crowd reaction to Bosingwa) was not going to help anyone. It was negative. He made a couple of errors but he didn't mean to do it and I took him off because we needed the crowd to be with us.
