An injury-time winner from Tom Ward broke Wroxham hearts as King's Lynn Town came from behind to book their place in the last four of the Norfolk Senior Cup.
Ward drilled home his second goal of the night following a goalmouth scramble from a Lee Stevenson corner.
The dramatic winner arrived after the giant defender had cancelled out Oliver Humphries first half effort for the Yachtsmen early in the second half.
Lynn's starting line-up showed four changes from the side that drew at Cirencester as visiting Wroxham started life under new boss David Coyle.
The first opportunity of the night fell the way of the hosts in the 13th minute when Toby Hilliard glanced a Kurtis Revan cross over the woodwork.
Hilliard then fluffed his lines inside the box as Lynn camped in the Yachtsmen's half during the opening 20 minutes. Revan was a constant thorn in Wroxham's side in the opening 45 minutes as higher-level Lynn looked to stamp their authority on the tie.
Wroxham took the lead five minutes before the interval when a Dan Quigley foul on the edge of the box was punished by Humphries who dilled home the resulting free-kick.
The opening goal stung Lynn into life but the Southern League outfit were unable to find an equaliser going into the break.
The Linnets were sent out early for the second half and they were soon back on level terms after Ward hammered home a Michael Clunan corner at the far post in the 49th minute.
Despite conceding, Wroxham refused to throw in the towel.
The gutsy Ryman League Division One North outfit went close to regaining the lead in the 76th minute when Humphries bent another set-piece over the woodwork. Warburton went close to snatching a late winner before Ward did just that with literally seconds left on the clock.
