Goalkeeper Seny Dieng scored in stoppage to rescue a comeback point for Queens Park Rangers at unbeaten Sunderland, who had led 2-0 for 47 minutes.
The Senegal keeper completed a remarkable fightback when he headed in two minutes into added time and still had time to make key saves, clawing one effort away, and was also fortunate that Elliot Embleton's effort struck the crossbar.
Sunderland's new strike partnership of Ellis Simms and Ross Stewart continued their bright start with first-half goals apiece to establish a 2-0 lead.
Stewart opened the scoring when he fired in after Dieng had denied Dan Neil, while Everton loanee Simms followed up his winning brace last weekend with a third for the Black Cats when he took an Alex Pritchard pass and prodded in.
