The only Sussex derby of the round was at Leylands Park, where Burgess Hill Town shocked the Isthmian premier division Rocks with a 2-0 win.
Lewis Finney gave Dean Cox’s team the lead after two minutes and Bognor could not find a reply – and Finney made sure of the upset with a second in the dying moments.

Also through are Lewes, who eased to a 4-0 win at Isthmian south east side Faversham thanks to goals by Kalvin Lumbombo-Kalala (2), Tommy Wood and Archie Tamplin.
Four Sussex sides face midweek replays.
Horsham will have a home replay against Leatherhead in midweek after a 0-0 draw in Surrey. The same goes for Whitehawk after a 0-0 draw at Sevenoaks.
Lancing will have to play it again after holding higher-division Carshalton to a 1-1 draw. Alex Laing put Dave Altendorff’s team ahead but it was cancelled out by Tommy Bradford 16 minutes from time.
Steyning are another Sussex team facing a replay – they drew 0-0 at Hadley. Newhaven’s first game at this stage since 1962 ended in a 5-1 defeat at Cray Wanderers – Rob Malila their scorer.
There’s one tie involving a Sussex side on Sunday – when Hastings go to Erith & Belvedere.
