United States international Geoff Cameron has joined Queens Park Rangers on a one-year contract with the option of a second year.
Cameron, 34, spent last season on loan to QPR from Stoke City making 19 appearances and scoring one goal.
"It's great to be back," Cameron said. "I really enjoyed my time here last year -- it's a family-orientated environment and this move is the best fit for myself and my family.
"The manager [Mark Warburton] wants to get the ball down and play good football. Hopefully myself and Angel [Rangel], who has also come back, can use our experience to help what is a young squad.
"I'm here to help the team in any way that I can -- whether that's leadership on the pitch or off it as well.
"For me, I'm excited for this role and I'm excited to be here. I just want to enjoy my football, like I did here last season."
"He is well-known by both the fans and the players, and his physicality is an asset as well.
"We're delighted to welcome Geoff back to QPR."
