Dominic Calvert-Lewin missed a first-half penalty as Leeds squandered a chance to win at Crystal Palace - but they did well to hold on for a point in the end after playing the second period with 10 men.
A dour match sprang to life just before half-time when Palace captain Will Hughes handled the ball from a Leeds corner.
Calvert-Lewin dragged his spot-kick wide of the left post, and it got worse before the break for the visitors.
Left wing-back Gabriel Gudmundsson was given a second booking for a foul on Ismaila Sarr in the centre circle, and was dismissed - after a short delay - by referee Tom Bramall.
That came shortly after Palace felt Leeds defender Jaka Bijol should have had a second yellow card following a coming together with Sarr. It led to a flashpoint on the touchline with head coaches Oliver Glasner and Daniel Farke both booked.
Palace struggled to break down the 10 men, with striker Jean-Philippe Mateta sent on.
It was the Frenchman's first league appearance since a move to AC Milan fell through before the transfer deadline, and just like on Thursday against AEK Larnaca he was booed by some home fans.
Mateta nevertheless came close to opening the scoring when deflecting a cross towards goal after 66 minutes, with Leeds keeper Karl Darlow having to parry the ball away.
Palace did have the ball in the net with 12 minutes to go when Jefferson Lerma bundled in from close range, but it was disallowed because Brennan Johnson was caught offside during the short corner routine in the build-up.
No winner means Leeds stay three points above the relegation zone. They are seven points behind Palace, who stay 14th.
