Gabbidon spent six seasons with the Hammers
QPR have completed the signing of Wales international defender Danny Gabbidon on a one-year contract.
The 31-year-old centre-half left West Ham United at the end of his contract this summer, having made 113 appearances in six years at Upton Park.
Gabbidon had been training with the Hoops and played in three friendlies on the club's recent tour of Cornwall.
He becomes manager Neil Warnock's third pre-season signing after Jay Bothroyd and his former team-mate Kieron Dyer.
"I'm delighted to be here," Gabbidon told the
club's official website
. "It's a good club. Hopefully I can learn more about it in the coming weeks. I had a good week with the lads in Cornwall and I'm pleased to have signed.
"He [Warnock] was a big part in me joining the club. I've been quite impressed by him. He's straight talking, which I like. If you're doing something right I think he'll be the first to tell you and, if you're not, he'll be the first to tell you again.
"As a player, that's what you want. I was impressed with what he had to say about the club and what he wants to do this season.
"Hopefully I can bring experience to the table having played in the Premier League for a number of years."
Warnock is delighted to add more top-flight experience to his team as they prepare for life in the Premier League after winning the Championship last season.
"He's impressed me in the last 10 days or so that he's been training with us," he said.
"I think he's just the type of player we need - a quality defender with plenty of experience. I hope I can reinvigorate his career, because a couple of years ago I thought he was one of the best defenders in the country."
