A late Kwesi Appiah strike gave AFC Wimbledon a thrilling 3-2 victory over League One rivals Fleetwood Town.
Andy Barcham opened the scoring for the Dons in the 16th minute, firing Mitchell Pinnock’s left-wing cross past Fleetwood stopper Alex Cairns.
And although the hosts dominated for the majority of the encounter, Wimbledon doubled their advantage against the run of play early in the second period.
Anthony Hartigan’s effort from the edge of the box appeared to seal the win for Wally Downes side (55) before Fleetwood scored twice in two minutes.
First Paddy Madden bundled home Ross Wallace’s set-piece (70) before Ched Evans won and converted a 72nd minute penalty.
However, with the game heading towards a replay, Appiah scored to ensure AFC Wimbledon progressed to the FA Cup Fourth Round for the first time in 16 years.
