QPR are looking to offload Toni Leistner before the start of the new season.
The German defender, who turns 29 next month, was signed on a free transfer from Union Berlin last summer and made captain by the then Rangers manager Steve McClaren.
But new boss Mark Warburton is unimpressed with Leistner and wants to install a new skipper.
Warburton has made it clear Leistner is not in his plans and the player has been made available to other clubs. There is every expectation he will be on the move soon.
Rangers are also looking to sell Massimo Luongo but have so far received no firm offers despite various expressions of interest.
Meanwhile, Geoff Cameron will have a medical on Thursday ahead of a move to QPR.
Cameron, who recently turned 34, revealed in March that he wanted to return to west London after his season-long loan from Stoke.
Rangers have since been confident that he would reach a financial settlement with Stoke, where he has a year remaining on his contract, and move to Loftus Road on a permanent deal this summer as a free agent.
And with Cameron now on the verge of finalising his departure from Stoke, QPR are planning to complete his signing in time for him to play in this weekend’s pre-season friendly against Watford.
Rangers, who will face Stoke on the opening day of the season, signed forward Jan Mlakar, 20, on a season-long loan from Brighton on Wednesday.
But they will have to bide their time in the all-important pursuit of a more seasoned striker, just as they did last summer when targeting Nahki Wells and Tomer Hemed.
This time around Rangers are pursuing West Ham’s Jordan Hugill and have also been offered a potential deal to take Jordan Rhodes on loan from Sheffield Wednesday.
Warburton would like to bring in Scott Hogan, who previously played under him at Brentford and is not in Aston Villa’s first-team plans.
