Mark Travers made a string of late saves as Bournemouth ended QPR's unbeaten record following a 2-1 win in the Sky Bet Championship.
The Cherries' victory sent them joint-top of the table and extends their own unbeaten start after West Brom could only draw 0-0 at home to Derby.
Bournemouth and QPR were two of three teams in the division still yet to lose prior to the encounter at the Vitality Stadium, but the visitors made a poor start on the south coast.
R's centre-back Rob Dickie was easily disposed by Jaidon Anthony and the Cherries youngster proceeded to fired home after 12 minutes.
It was 2-0 before the break when Anthony picked out Dominic Solanke inside the area and the forward found the net.
Sam McCallum pulled one back after the interval for QPR but they could not find a way past the resilient Travers for an equaliser. The Republic of Ireland keeper repelled them the London club on numerous occasions late on to deny the visitors a point.
"Mark is growing, is listening and working tirelessly on the bits he needs to improve," said manager Scott Parker afterwards. "I thought he was very good at dealing with high balls and he pulled off some good saves when he had to. It was a big performance from him."
Jason Knight, meanwhile, returned to the Derby County starting line-up and almost notched a late winner for Wayne Rooney's side as they registered a goalless draw against table-toppers West Brom.
The recently-relegated side had plenty of chances but could not find a way past Kelle Roos and may lose top spot if Fulham win at Birmingham on Wednesday. Knight, himself, had the away team's best chance but his effort was deflected over.
Ben Brereton Diaz struck for the fourth time this season to inspire Blackburn to a 2-0 triumph over Hull at Ewood Park.
Daniel Ayala made the breakthrough with 61 minutes played before Chile international Brereton Diaz drilled into the corner with aplomb to send Rovers up to seventh. Meath's Darragh Lenihan operated at the heart of the defence for Blackburn as they kept a clean sheet and inched up the table.
Sheffield United were denied a second consecutive win after Emil Riis Jakobsen netted in the fifth minute of stoppage time to earn Preston a 2-2 draw on the road.
Sander Berge looked to have given Slavisa Jokanovic's side all three points with six minutes left after an opener for the Blades by Morgan Gibbs-White was cancelled out by Daniel Johnson.
Ireland international teammates, John Egan and Seanie Maguire, lined up opposite one another, though the latter was withdrawn with 19 minutes remaining.
But Jakobsen atoned for an earlier error when he rifled home in front of the away fans to clinch a point at Bramall Lane.
Blackpool have dropped into the bottom three after Reading got the better of Peterborough by a 3-1 score to move out of the relegation zone.
John Swift and Tom Dele-Bashiru struck in the space of three second-half minutes and while Nathan Thompson pulled one back for Posh they could not find a leveller and were then hit with a third late on.
Dele-Bashiru added a second in stunning fashion with a powerful effort from outside the area to leave Peterborough in 23rd. ROI underage international Conor Coventry featured in the centre of midfield for the relegation strugglers.
Huddersfield leapfrogged QPR to sit fourth in the table after an excellent 3-0 win at Blackpool.
Josh Koroma got the ball rolling for the Terriers with a stunner early into the second half and Matty Pearson and Jonathan Hogg joined him on the scoresheet to make it four victories already this term.
