Hendon fell to a third consecutive defeat of the campaign as they lost an early lead to fall 2-1 at Poole Town.
After Joe White had limped off early on, his replacement Hamza Semakula opened the scoring after 13 minutes, an advantage that they held until the 62nd minute when Jamie Whisken levelled things up.
The league's top scorer Tony Lee sealed the points for the Dolphins in the 83rd minute to secure the points for the home side and leave Hendon to rue another squandered lead.
