Brighton’s home Sky Bet Championship match against Cardiff was called off due to thick fog on Friday night.
Chris Hughton’s Seagulls side would have secured top spot to end 2016 with victory but the postponement meant Newcastle had the chance to return to the summit of the table.
Heavy fog on the south coast put the game in doubt and, less than two hours before the scheduled kick-off, Brighton released a statement saying: “The match has been called off after consultation between match officials and both clubs.”
Newcastle host Nottingham Forest at St James’ Park with the chance to reclaim top spot. Rafa Benitez’ side are looking to bounce back from a 1-0 home defeat to Sheffield Wednesday on Boxing Day.
