Substitute Jamie Mackie's late double was not enough to stave off defeat for QPR, who went down to a 3-2 defeat at Blackburn Rovers.
The Scot came from the bench to notch a tap-in first on 71 minutes before adding another with a stunning strike in second-half stoppage time, but Mark Hughes' men probably left themselves with too much to do after falling three goals behind before the break.
Yakubu put Rovers into the lead on 15 minutes, before Steven Nzonzi doubled the home side's advantage eight minutes later.
Junior Hoilett added what proved to be a crucial third on the stroke of half-time.
Despite defeat, Rangers remain outside of the bottom three in the Barclays Premier League on goal difference.
Hughes made three changes to his R's side from last weekend's defeat at home to Wolves for the trip to Ewood Park.
Fitz Hall, Akos Buzsaky and Armand Traore replaced Luke Young (hamstring), Shaun Derry and Djibril Cisse (suspended) respectively.
Blackburn, meanwhile, handed a first start to Bradley Orr, who joined Rovers on deadline day of the January transfer window from QPR, while Yakubu returned to the starting XI for the hosts after serving a suspension.
Rangers set-up in a 4-4-1-1 formation, with Paddy Kenny in goal behind a back four of Nedum Onuoha, Hall, Anton Ferdinand and Taye Taiwo.
Shaun Wright-Phillips began from the right-hand side of midfield, with skipper Joey Barton and Buzsaky in the middle and Traore out wide on the left.
Adel Taarabt played just behind Bobby Zamora.
The opening stanza was understandably tight, with both sides failing to create any chances of note inside the first ten minutes.
The first real opportunity of the contest came on 15 minutes - and with it arrived the opening goal for Rovers.
A free-kick from deep was flicked on by the head of Nzonzi into the path of Yakubu, who took a touch to control the ball before lashing an effort into the bottom left-hand corner from the edge of the box.
Eight minutes later, Rovers left QPR stunned when they added a second goal.
Nzonzi - provider of the first - stole possession in midfield before finding Hoilett down the left.
Thereafter, the diminutive winger cut in to the box before finding Nzonzi on 16 yards, who powered an effort home past Kenny and into the top left-hand corner.
The R's created their first attempt just a minute later but that wasn't to trouble Rovers keeper Paul Robinson, as Taiwo blasted an effort high and wide of the target from distance.
Rangers' best chance of the half arrived just past the half-hour mark.
Barton's corner from the right caused all sorts of confusion in the Rovers box before the ball eventually fell to Zamora, whose backward hook with his left foot crept just inches wide.
QPR fashioned another chance on the stroke of half-time.
Zamora ran on to Barton's long ball over the top of the Blackburn defence before cutting the ball back from the left for Traore, whose low drive from 18 yards was comfortably held by Robinson.
Play then switched to the other end, where Rovers stretched their lead to three goals just moments before the break.
Morten Gamst Pederson's long free-kick was headed down by Scott Dann, before Hoilett arrived at the left-hand post to smash a deflected effort home via the underside of the bar.
Rangers started the second period brightly, creating the opening chance of the half. Wright-Phillips' lofted cross found Zamora, whose header went handsomely wide of the right-hand post.
Blackburn almost added an outrageous fourth on 53 minutes.
Pedersen's miscued strike rolled kindly into the path of Yakubu, whose spectacular lob from 25 yards crashed off the face of the bar before the danger was cleared.
QPR huffed and puffed in an attempt to try and muscle their way back into the match.
Onuoha perhaps should have done better when he could only fire an effort straight at Robinson from ten yards, following Taarabt's sumptuous slide-rule pass.
Hughes decided to freshen things up come the 66th minute, with Mackie introduced at the expense of Buzsaky. The R's switched to a 4-3-1-2 formation in the process.
Four minutes later, good work from Taarabt and Wright-Phillips eventually saw the latter free Taiwo down the left, but the Nigerian full-back could only fire wide of the near post.
A change in system saw a marked improvement in the R's, who pulled a goal back courtesy of substitute Mackie 19 minutes from time.
Play eventually swung the way of Taiwo down the left before the defender drove into the box and picked out Mackie, who got in front of his marker to prod home from six-yards out.
The goal appeared to lift Rangers and Robinson had to be at his best on 85 minutes to thwart Taarabt, after the Moroccan let fly with an effort from just inside the box.
Wright-Phillips, meanwhile, also went close with a rasping drive that flashed past the upright a minute before time.
Four minutes of second-half stoppage time went up on the board - and Mackie made sure of a nervy finish for Rovers with a splendid strike.
The industrious forward turned his marker on the edge of the box after Taarabt's clever pass, before drilling an unstoppable shot into the top left-hand corner.
Rangers' late show was to be in vein, however, as the hosts clung on for victory.
