Colney Heath are through to the semi-final of the Dudley Latham Memorial Cup after beating local rivals London Colney 2-1 on Tuesday night.
The game was moved to the Recreation Ground because of pitch issues at Cotlandswick and the Magpies made home-field advantage count as they took a two-goal lead, first through Josh Humbert and then Levi Gunn.
James Ewington pulled one back for the Blueboys after good work from Jimmy Hill, but Heath held out to set up a last four tie against St Margaretsbury or Hertford Town.
