League Two Cambridge United reached the fourth round of the FA Cup for the first time in 15 years with a 2-1 victory against Luton Town.
Forward Robbie Simpson gave the hosts the lead in the first half when he poked in after his penalty was initially saved.
Ryan Donaldson slotted in a second after the hour, but defender Michael Harriman pulled one back with a header.
Jonathan Smith shot just wide for Luton but Cambridge held on.
It is the first time Cambridge have progressed this far in the competition since the 1999-2000 season, and it was a deserved win for Richard Money’s side.
Luton will perhaps rue a miss by Andy Drury, who failed to hit the target despite being presented with an open goal early in the second half.
That would have cancelled out Simpson’s opener, which came midway through the first half.
Luton keeper Mark Tyler brought down Donaldson inside the area and Simpson stepped up to take the resulting penalty. Tyler parried it on to the post but Simpson reacted quickly to fire home.
Donaldson hit the crossbar in the second half but made no mistake when he latched on to Tom Champion’s ball and slotted home.
Harriman set up a tense finish when he headed in Drury’s cross soon after Donaldson’s goal and although the visitors pressed in the closing stages, they could not force an equaliser.
