Leeds midfielder Pablo Hernandez salvaged Marcelo Bielsa's unbeaten start to the season with an equaliser in the 2-2 draw against former club Swansea.
Ex-Elland Road academy player Oliver McBurney had looked like upsetting his old club with two goals either side of Kemar Roofe's fourth of the campaign.
However, Hernandez swept home 10 minutes from time and, although Leeds lost the SkyBet Championship's only remaining 100 per cent record, a point was enough to take them top of the table on goal difference from Middlesbrough.
The draw also lifted Swansea, still unbeaten themselves, into third place.
At the other end of the table QPR extended their unwanted 100 per cent record with a fourth successive defeat after losing 3-0 at home to Bristol City.
