Newcastle were held to a goalless draw by Crystal Palace after having a goal controversially ruled out by the video assistant referee.
The hosts were denied when it was eventually ruled that Joe Willock had fouled Vicente Guaita as Tyrick Mitchell put the ball into his own net.
But replays showed how Mitchell appeared to push Willock into the Palace goalkeeper, much to the disgust of the home crowd when the incident flashed up on a big screen.
Earlier, Newcastle were left further frustrated after record signing Alexander Isak fluffed an attempt to dink the ball over Guaita when clean through, while Miguel Almiron also hit the post with a deflected shot.
Willock should have earned the win late on when he shinned an effort from two yards out following another effort that drew a fine save from Guaita.
Palace - who, like Newcastle, have only won once this season - didn't severely test home goalkeeper Nick Pope until a late improvement, when Odsonne Edouard's close-range shot forced him to save.
However, the point will be welcome for Patrick Vieira's side, who earned their third draw of the season.
Newcastle are now winless in five games for the first time under manager Eddie Howe.
Howe later said: "It was an incredible game. Two teams going at it trying to deliver. Barring a slow start - or maybe a 15-20 minute period in the middle of the first-half - the lads gave me everything. How we have jot scored, I'll let you look back and decide.
"There were more presentable ones [than the Alexander Isak chance]. Everything we tried in and around the goal didn't work, even the one we did score. I disagree with the decision. I thought it should be a goal. I thought Joe was pushed. He is running in and is pushed into the keeper. I am not sure what Joe is supposed to do there. For me it is a perfectly good goal.
"You hope it is not one of those days where you get caught by a sucker punch. I have to credit my players for not losing focus and discipline. In terms of effort and the team pulling together it has been really good. We should have more points. One win and a few draws that should be wins, but it is a long season. Performance levels are really good. I hope the football gods level it up and we get points maybe when we're not playing so well."
