The Spireites reserve side face an unexpectedly-huge test against Notts County tomorrow, with the Magpies set to field a first-team squad for the game.
The Central League Cup game at Sheffield FC's Coach and Horses Ground (postcode: S18 2GD) kicks-off at 1pm with free admission for all supporters.
The Magpies' first team have lost their last three games and ahead of their trip to North Derbyshire manager John Sheridan announced
that all first-team payers would be involved in the game.
By contrast, Ritchie Humphreys' side will consist of mainly young players, with the Spireites squad currently severely stretched due to a series of injuries.
"It's a huge opportunity for our lads," said Humphreys. "Reserve team football can be like that. Teams change from week to week and rarely do you get a settled side. We'll have a really young team tomorrow, with a couple of young professionals and some scholars.
"It will be a good step up for them and the games they've been playing. We've been able to catch them a couple of times when they've been playing in the FA Youth Cup and I'm looking forward to working with them tomorrow.
"We now know it will be a strong Notts County side but that's what football's about and why I think reserve team football is good - as you may be up against a player with 300 league appearances so you can see how they cope with that as a team and as individuals and it's up to us to help them and get something positive out of the game."
