QPR are hoping to seal the signing of Republic of Ireland midfielder Liam Miller from Sunderland in the next 48 hours.
Sunderland are happy to let Miller leave but the player may move to west London on an initial loan deal.
Miller, who turns 28 next month, was transfer-listed last year after repeatedly turning up late for training.
No other clubs have since come in for him but Rangers made enquiries after Ireland boss Giovanni Trapattoni spoke highly of Miller during a recent visit to Loftus Road.
QPR also lined up Tottenham outcast Hossam Ghaly as a possible signing but look more likely to land Miller, who was at Celtic and then Manchester United before joining Sunderland on a free transfer in 2006.
And Rangers are still pursuing midfielder Ben Watson, who is expected to leave Crystal Palace before the transfer window closes.
A number of Premiership clubs have been watching Watson closely for a long time but have decided against making a firm move to sign him and unless that changes, Rangers remain in pole position.
Meanwhile, the club are waiting to see if any bids are tabled for Mikele Leigertwood, who will be allowed to leave for £1million if an offer comes in and Rangers can secure another midfielder.
They were again reliant on Dexter Blackstock on Saturday, when the striker’s late equaliser – his 12th goal of the season – rescued a 1-1 draw against 10-man Coventry.
Sky Blues defender Stephen Wright was red-carded following a first-half challenge on Heidar Helguson, but Rangers struggled to make their numerical advantage count and fell behind to Dan Fox's 73rd-minute free-kick.
That looked like giving Coventry maximum points but Blackstock levelled with three minutes remaining.
Damion Stewart's long ball was flicked on by Samuel Di Carmine and Blackstock nipped in front of Ben Turner to head past goalkeeper Keiren Westwood.
Boss Paulo Sousa admitted he made a mistake by switching from his preferred 'diamond' formation to 4-4-2 in order to give a debut to Wayne Routledge following the winger’s £500,000 move from Aston Villa.
Sousa said: "We changed our shape and played without training very much because the weather gave us few opportunities to train.
"When this happens it is better to keep playing the way we were before, so I take responsibility for this.
"We looked for a winger and when Wayne came, we wanted to be more open and play with more width. We lost some control in midfield, where we had been playing with four in the middle.
"When you change things it doesn't just click. We want to play a different way, but it does take time. But the positive thing is that we are building. It's coming."
