Juventus defender Mauricio Isla has completed terms on a season-long loan deal with QPR, with the London club awaiting work-permit confirmation.
The 26-year-old Chilean should see his QPR move confirmed once the club receive official endorsement on the transfer from the Football Association.
Manager Harry Redknapp has secured Isla's services on a one-year loan with a view to a permanent transfer, Press Association Sport understands.
The 47-cap Chile defender has completed his medical at Loftus Road and tweeted news of his move on Tuesday morning, before later removing the post.
Redknapp's fourth summer signing should be officially ratified just a day after QPR paid a fee believed to reach £6million to prise Jordon Mutch away from Cardiff City.
