Redknapp defends Bosingwa after QPR fans' abuse
The former Chelsea fullback was at fault for both of Toon's goals in their 2-1 win.
"They were horrendous goals, both of them," he said.
"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.
"People pay their money, we all get grief at some stages but it has been a miserable season."
