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.
