Newcastle United 2 Brighton & Hove Albion 1
Albion lost their fourth consecutive Premier League match and have fallen back into the bottom half of the table.
The Seagulls are now just five points ahead of Newcastle but still have 12 points more than Burnley who currently occupy the final relegation position.
Two quick first-half goals from Ryan Fraser and Fabian Schar gave the Toon what turned out to be an unassailable lead.
Albion had first-half chances with Tariq Lamptey, Shane Duffy, Jakub Moder and most notably Danny Welbeck all going close – Welbeck seeing an effort well saved by Martin Dubravka.
The Seagulls pulled a goal back in the second half with Lewis Dunk heading in his first of the season.
Both teams had good chances to add a fourth, with Solly March and Dunk both forcing saves from Dubravka.
Substitute Allan Saint-Maximin caused the Seagulls some problems late on but the Seagulls look to be in free fall.
The next two matches are at home to Liverpool, next Saturday (12 March), then Brighton host Tottenham Hotspur five days later in a rearranged home fixture.
