Bury 1-3 Wycombe
Wycombe remain in the driving seat for automatic promotion from League Two thanks to a Ben Strevens brace at already-promoted Bury.
Ryan Lowe put the hosts in front from the penalty spot after Dave Winfield handled his initial effort.
Gareth Ainsworth headed in the equaliser for the Chairboys from a Stewart Lewis cross.
Strevens poked home after Scott Rendell flicked on before sealing the win from close range after a corner.
Bury's defeat means that Chesterfield only need a point next week to secure the League Two title.
Wycombe only need to match Shrewsbury's result to confirm their own promotion to League One.
Bury caretaker manager Richie Barker told BBC Radio Manchester:
"It wasn't our day and fair play to Wycombe they came and made it difficult for us.
"They are a good young bunch of athletic footballers, but I think today was probably a little bit of a step too far for them.
"What we have achieved is excellent and all credit to everyone who has been involved."
