Leeds United were forced to settle for a point after playing the entire second half with 10 men in a goalless draw against Crystal Palace at Selhurst Park.
The match had been largely uneventful until just before half-time when Palace captain Will Hughes handled the ball from a Leeds corner, giving the visitors a golden opportunity to take the lead.
However, Dominic Calvert-Lewin dragged his penalty wide of the left post, wasting a huge chance for Leeds.
Things quickly worsened for the visitors.
Moments before the break, Gabriel Gudmundsson was shown a second yellow card for a foul on Ismaila Sarr in the centre circle, leaving Leeds to play the entire second half with 10 men.
Tempers had already begun to rise earlier in the half when Palace felt Leeds defender Jaka Bijol should have received a second booking after a challenge on Sarr.
The incident sparked a touchline confrontation between head coaches Oliver Glasner and Daniel Farke, with both managers being shown yellow cards.
Despite their numerical advantage, Palace struggled to break down Leeds after the break.
Striker Jean-Philippe Mateta, making his first league appearance since a proposed move to AC Milan collapsed before the transfer deadline, nearly broke the deadlock after 66 minutes.
His deflected effort forced Leeds goalkeeper Karl Darlowinto a sharp save.
Palace thought they had found a winner late in the game when Jefferson Lerma bundled the ball into the net from close range.
However, the goal was ruled out after Brennan Johnson was caught offside during the short corner routine in the build-up.
The result leaves Leeds three points above the relegation zone, while Palace remain 14th in the table.
Calvert-Lewin had arrived at Selhurst Park with a strong record against Palace, having scored seven Premier League goals against them - more than against any other top-flight opponent.
Leeds boss Farke had taken a late fitness gamble on the striker after a recent knee issue, and the forward initially looked lively.
He tested Palace debutant goalkeeper Walter Benitez with a powerful header and also forced a last-ditch clearance from Johnson.
But his missed penalty proved to be the turning point in a chaotic five-minute spell that also saw Gudmundsson sent off.
To their credit, Leeds remained organised and resilient in the second half, with captain Ethan Ampadu delivering an impressive performance in midfield as they battled for a hard-earned point.
However, with Nottingham Forest dropping points against Fulham, Leeds may feel they missed an opportunity to open up a bigger gap above the relegation zone.
Palace manager Glasner was forced into an unexpected change before kick-off as captain Dean Henderson missed the match through illness after starting 77 consecutive league games.
His replacement, Benitez, handled Leeds’ aerial threat well and made several important interventions.
While Palace defended solidly, their attacking struggles continued.
This was their second goalless home draw in four days following a UEFA Europa Conference League stalemate with AEK Larnaca.
Palace have now scored just seven league goals from open play at home this season - the lowest total in the division - and their lack of cutting edge was highlighted by their failure to create clear chances even against 10 men.
In fact, they became the first Premier League side on record not to register a shot on target against an opponent who had a player sent off in the first half.
