Danny Welbeck scored an extra-time winner as Brighton beat Newcastle to reach the FA Cup quarter-final after an incident-packed tie that ended 10-a-side.
The Magpies thought they had booked their place in the final seconds of normal time, but Fabian Schar’s cushioned volley was disallowed for offside by the video assistant referee (VAR).
Newcastle had taken a 22nd-minute lead through an Alexander Isak penalty, but Yankuba Minteh levelled just before half-time against the club that sold him in the summer.
Both teams had players sent off in a dramatic climax.
Newcastle’s Anthony Gordon was shown a straight red card in the 83rd minute for pushing Jan Paul van Hecke in the head – a decision that will rule him out of the Carabao Cup final against Liverpool through suspension.
Brighton defender Tariq Lamptey was then dismissed in added time at the end of 90 minutes for a second booking following a late challenge on Jacob Murphy.
The game looked as if it would be going to penalties before Solly March played in Welbeck with six minutes left and he calmly chipped home keeper Martin Dubravka to send the away fans wild.
It was Welbeck’s eighth goal of the season and the 34-year-old – who won the FA Cup twice with Arsenal – also netted the winner in Brighton’s Premier League game at Newcastle in October.
