Mansfield 0-1 Cambridge highlights
Sullay Kaikai scores the only goal as Cambridge United beat Mansfield to set up a third-round clash at home to Luton Town.
Following a 2-2 draw last week, Kaikai had the U's in front early on in the replay when his 20-yard effort took a wicked deflection past Sascha Studer.
Mansfield's Luke Waterfall thought he had hooked in a dramatic late equaliser, but it was ruled out for offside.
