QPR have accepted an initial offer of £1.5m from West Bromwich Albion for defender Danny Shittu.
Shittu has made more than 160 league appearances for QPR
The Baggies have struck a deal which could rise to £3m according to his performance and that of the club.
The 25-year-old is set to travel to the Hawthorns on Friday discuss personal terms and undergo a medical.
WBA boss Bryan Robson wants to bring in defensive cover for Neil Clement and Thomas Gaardsoe who will both miss the start of the season through injury.
QPR chairman Gianni Paladini had previously insisted his club would not accept less than £3m for defender Danny Shittu.
Watford had a bid for the giant centre-back rejected.
Shittu moved to Loftus Road from Charlton in 2002 in a £350,000 deal funded by QPR fans Matthew and Alex Winton.
He has since made 162 league appearances and is a firm favourite among supporters.
