Darlington 0-1 Gateshead
Jon Shaw scored an injury-time winner to boost Gateshead's play-off bid as they beat local rivals Darlington.
With a goalless draw looking on the cards, Shaw headed home Craig Baxter's cross from close range.
That winner came seconds after team-mate Yemi Odubade had smashed a shot against the crossbar.
Darlington had chances before the late drama, with Ryan Bowman, Adam Rundle and Dale Hopson forcing saves from away goalkeeper Tim Deasy.
