QPR have confirmed the signing of Jake Clarke-Salter.
The centre-back, 24, recently agreed to join on a free transfer after being released by Chelsea at the end of his contract.
He has signed a three-year deal with the option of a further year.
Clarke-Salter, a former England Under-21 international, spent last season on loan at Coventry, who were keen to sign him on a permanent basis.
He is well known to new QPR head coach Michael Beale, who previously coached in the academy at Chelsea.
Clarke-Salter made two first-team appearances for the Blues.
He has also had loan spells at Bristol Rovers, Sunderland, Birmingham and Dutch club Vitesse Arnhem.
“I am over the moon,” Clarke-Salter told the club website. “It’s a permanent deal and it’s time for me to settle down and progress in my career.
“It’s totally different to a loan move because this is my home and I am fully focused on doing great things with this club.
“This is a big step for me and one I am totally ready for.”
The club have once again been trying to agree a deal for George Cox with Dutch club Fortuna Sittard and are due to hold talks with Dutchman Kenneth Paal, who has emerged as a possible alternative.
Cox, 24, has a year remaining on his contract.
Paal, also 24, is available on a free transfer after recently leaving PEC Zwolle.
Rangers are also looking to bring in a striker, with a number of potential deals currently being looked at.
