The Spireites have impressed Andy Hessenthaler, boss of last weekend's hosts Dover, by escaping from relegation trouble in the second half of the season.
Town have won nine of their 16 games under Sheridan and secured safety on Saturday with their 0-0 draw at Dover.

"We weren't great," he said.
"It wasn't a great spectacle as a game. It's hard to fault the boys, they kept going.
"We were the better side certainly second half, pretty much on top, just couldn't break them down.
"Their big lad came on near the end and he caused problems, he's going to, he's a good player."
Hessenthaler took Chesterfield's much-changed line-up into account when assessing the result.
Sheridan gave keeper Joe Anyon his first start of the season, handed Jack McKay his full debut and brought Marc-Antoine Fortune, Lee Shaw, Robbie Weir, Kyel Reid and Charlie Carter into the starting line-up.
The Dover boss praised the Spireites for getting to the position of safety that permitted those changes.
"They've made some changes, gave players out of contract a chance to impress the manager," said Hessenthaler.
"They've done fantastic to get out of the position they were in."
