Geoff Cameron says he was treated unfairly by former Stoke City boss Gary Rowett.
Cameron, 33, moved to QPR on a season-long loan after being told he was not in Rowett’s plans.
And the American told West London Sport he was shunned by Rowett, who has since been replaced by Nathan Jones.
“He didn’t really give me a chance, which was disappointing,” Cameron said.
“First he said he wanted me to stay and that I wouldn’t be leaving. Then as soon as the window for permanent transfers closed he said I wouldn’t be playing and that it might be better if I went and played somewhere else.
“Fortunately, Steve McClaren then came and said ‘Hey, I want you to come and play for me’ and I’ve really enjoyed it at QPR, it’s just really frustrating that I got injured when I did.”
Even with Rowett having left, Cameron does not believe he will play again for Stoke, where his contract runs until 2020.
He has indicated that he would like to return on loan to QPR for another season if a deal can be agreed between the two clubs.
“We’ll see what happens in the summer but my target at the moment is to get back playing again,” said Cameron.
“I felt I was playing my best football in a long time, and the team were playing really well, and then this injury came along.”
