Leeds United striker Chris Wood netted a last gasp equaliser to cancel out Jamaal Lascelles opener, as Newcastle failed to keep pace with Brighton at the top of the Championship.
Having seen Huddersfield win late in the day, and the Seagulls claim victory on their travels the pressure was on Rafa Benitez's United to produce the good to stay within touching distance at the top.
But a late, late Wood finish denied the Magpies, who can feel a certain sense of injustice, having dominated proceedings from start to finish.
Benitez made two changes to the side humbled at Sheffield Wednesday last weekend - Aleksandar Mitrovic came in for the injured Dwight Gayle, with Isaac Hayden slotting into midfield for Mo Diame.
Despite a bright start it was the visitors who drew first blood - Pablo Hernandez struck Karl Darlow's upright, and then from the rebound the Magpies' stopper reacted quickest to beat away Kemar Roofe's header.
Yoan Gouffran was next to hit the woodwork - his low effort cannoned off the post as United began to assert their dominance over the Whites.
In fact, United can think themselves unlucky not to go in one goal to the good having enjoyed a period of dominance which saw Matt Ritchie, Chancel Mbemba and Ayoze Perez go close.
The Magpies continued to ramp it up in the second-half, peppering Rob Green's goal with efforts, but despite dominating possession and they couldn't find the breakthrough.
Mbemba had an appeal for a penalty waved away by Christopher Kavanagh, despite the fact he appeared to be pulled to the ground by Luke Ayling.
Mitrovic then went close on the hour when he pounced on a short header back to Green, flicked it over the onrushing former England international, before his efforts were thwarted by Pontus Jansson.
The breakthrough finally came in the 67th minute - a hopeful ball into the area by Gouffran was nodded back across goal by Mitrovic and Lascelles turned home from six yards. It was nothing less than United deserved.
Not content with their one goal advantage United went in hunt of a second - Mitrovic, impressive on return, tested Green, while Jonjo Shelvey struck wide from distance.
United looked all set to see out the encounter with minimal fuss to move to within two points of Chris Hughton's men at the top, but Wood had other ideas.
A hopeful ball into the area caught the United backline napping at Wood stole in to hand Brighton the advantage at the second tier summit.
