Little Maidstone United have reached the FA Cup fourth round for the first time in their history, pulling off the day’s biggest shock in the famous old competition by defeating League One Stevenage at their overjoyed Gallagher Stadium.

Sam Corne’s penalty just before halftime on Saturday proved enough for the National League South side as Stevenage, three divisions above them, paid the price for near-misses when both Jamie Reid and Kane Hemmings hit the woodwork early in the second half.

National League (fifth-tier) Eastleigh will join Maidstone in the fourth-round draw after a Chris Maguire penalty sealed a 1-1 draw with Newport at Rodney Parade.

Elsewhere, there was heartbreak for National League leaders Chesterfield, who led at Championship side Watford for much of the game before eventually being beaten 2-1, sunk by a stoppage-time strike from Tom Dele-Bashiru.

Joe Quigley’s 28th-minute header for Chesterfield evoked memories of their famous run to the 1997 semi-finals, but Mileta Rajovic came off the bench to level and Dele-Bashiru denied the visitors a second chance when he struck in the fifth minute of added time.

Bournemouth were forced to battle back from two goals down to escape an upset against QPR at Loftus Road.

Goals from Sinclair Armstrong and Lyndon Dykes gave Rangers a 2-0 halftime lead, but Marcus Tavernier reduced the deficit after the re-start.

Brighton fell behind early at Stoke after an own goal from Jan Paul van Hecke, but goals from Pervis Estupinian and the returning Lewis Dunk put them in command before the hour mark.
