Erith and Belvedere made club history by reaching the last eight of The FA Vase for the first time after coming from behind to win 3-2 at Holbeach United, with Adam Marsh's winner for the visitors coming in the tenth minute of extra time.
The Kent Southern Counties Eastern League side were a goal down after only three minutes when Lee Dube put Holbeach ahead, but Erith equalised ten minutes later when Byron Walker ran on to Marsh's long ball to shoot home.
Dere then took the lead in the 34th minute through an own goal from Holbeach but the Lincolnshire side equalised with 20 minutes remaining when Jake Duffy scored.

With the scorea tied after 90 minutes, extra time commenced. It was Marsh who settled it in Erith and Belvedere's favour when he smashed the ball into the top corner of goal in the 100th minute of a pulsating cup-tie.
Elsewhere, Glossop North End and Dunston UTS will have to play again after a 2-2 draw, also after extra time. Dunston took the lead in the 63rd minute when Andrew Bulford opened the scoring, but the home side equalised two minutes later through Kelvin Lugsden.
The game exploded into life in the 75th minute when Dunston's Luke Gilhespy was sent off for his second yellow card with a foul and from the resulting penalty Tom Bailey put Glossop into the driving seat.
But with eight minutes remaining, Gary Ormston equalised for Dunston, and the ten-men held on through the extra half-hour to earn a replay back in the North East.
