Former Leeds United backroom staff man Carlos Corberan had to settle for a draw on his return to Elland Road with West Bromwich Albion.
Corberan's Baggies looked set to steal all three points with Brandon Thomas-Asante's controversial 52nd-minute opener.
Jayson Molumby's shot clearly deflected off Thomas-Asante's arm - and the goal stood.
But, despite the heroics of visiting keeper Alex Palmer, who made two fine saves from Dan James in both halves, Leeds kept their heads - and skipper Luke Ayling levelled.
