You can watch brief highlights of a controversial and thrilling encounter at Vale Park on Friday afternoon.
Vale took on fellow strugglers Chesterfield in a must-win game and took the lead through a rare Danny Pugh goal before the midfielder was promptly sent-off for a poor challenge.
Chesterfield equalised through a free-kick before substitute Ben Whitfield kept his composure to finish and put Vale ahead in the closing stages.
The result saw the Valiants ease the pressure and boost their chances of escaping the League Two trapdoor.
