Mark Wright had given the home side the lead side-footed an effort across keeper Barry Roche after latching onto Lloyd Dyer's cross.

Chesterfield pressed for a leveller and were rewarded when Adam Rooney crossed for Felix Bastians to slam home.

They completed their comeback as Jamie Ward reacted quickest to Jamie Lowry's cross and neatly finished inside the near post.
