Leeds pushed bottom-of-the-table Sheffield United closer to relegation with a 2-1 win against their Yorkshire rivals at Elland Road.
Jack Harrison put Leeds ahead with a 12th minute tap-in from Raphinha's cross.
The Blades equalised in first half stoppage-time, with Ben Osborn nudging Oli McBurnie's deflected shot over the line despite Luke Ayling's attempt to block.
In the 49th minute, Blades defender Phil Jagielka turned Harrison's cross into his own net, leaving the visitors 14 points from safety with only eight games left.
