Leeds left the door open for Leicester and Ipswich to increase their leads at the top of the Championship after a 1-1 draw at managerless Rotherham on Friday night.
Crysencio Summerville gave Daniel Farke's men the lead with a superb solo effort after only six minutes, but right on the stroke of half-time, Hakeem Odoffin fired a clinical equaliser past Illan Meslier to restore parity.
Leeds - who had 18 shots and 74 per cent possession on the night - thought they had won the game late on, when substitute Jaidon Anthony slammed in Willy Gnonto's square ball, only for the offside flag to swiftly follow celebrations.
The third-placed visitors have narrowed the gap to the current top two to seven points, but they could find themselves 10 points outside the automatic promotion places on Saturday night, should they beat Swansea and West Brom respectively.
Rotherham - currently led by caretaker Wayne Carlisle after Matt Taylor's sacking - move to within three points of exiting the relegation zone.
Leeds set their stall out early at the New York and, before the game had had a chance to settle into a rhythm of any sort, they were in front.
Glen Kamara fed Ethan Ampadu, whose crisp pass found Summerville on the left. The Netherlands U21 international beat the offside trap, quickly broke into the area and deliciously curled in his seventh goal of the season.
Farke's side dominated the ball thereafter and probably should have extended their lead as a result. Summerville drew a strong save from Viktor Johansson and Kamara blasted into the side netting, with Joel Piroe wasting a couple of chances, too.
Instead, in first-half stoppage-time, Rotherham levelled with their first shot on target. Christ Tiehi's slide helped the ball into the Leeds area, from where Odoffin clinically equalised after the ball took a fortunate nick off Joe Rodon's leg.
They almost turned the game in their favour just after the break, too. Ampadu's poor header was seized on by Sam Nombe, whose shot beat Illan Meslier, only for Liam Cooper to arrive on the scene and make the crucial block.
Chasing the win, Farke sent on Gnonto, Patrick Bamford and Ian Carlo Poveda. Subsequently, Gnonto lashed an effort over, Bamford's pot-shot skipped wide, while fellow sub Pascal Struijk headed a ball to the back post agonisingly wide under little pressure.
Leeds thought they had completed the job late on when Anthony prodded in Gnonto's cross after a spell of intense pressure, but the offside flag came to Rotherham's rescue, with Bamford having strayed as he tried to attack it first.
