Martin Rowlands' super-strike sent Wolves spinning to a first defeat in nine games with a 1-0 defeat to QPR cutting their lead at the top of the Coca-Cola Championship to three points.
The QPR captain hit a stunning goal midway through the second half at Loftus Road to dent Wolves' promotion hopes and fire his own side into the play-off picture.
Rangers were good value for their win in what was new boss Paulo Sousa's sternest test since he took over last month.
The former Portugal midfielder passed with flying colours while opposite number Mick McCarthy became the latest victim of the Manager of the Month curse.
McCarthy's side, who had won seven of their previous eight games, were uncharacteristically jittery at the back, while their 27-goal strikeforce of Chris Iwelumo and Sylvan Ebanks-Blake barely had a sniff.
