Gresley hung on to make it through to the last eight of the FA Vase.
A goal down on 11 minutes the visitors levelled just before the break through Royce Turville.
On the hour Gresley took the lead with a spectacular goal from Turville and Rob Spencer added two more in the space of three minutes but late goals from Dan Chilton and Jon Crockett meant a nail biting incredible nine and a half minutes of added on time but the visitors hung on.
Final Score: Long Buckby 3 - 4 Gresley
