After a challenging Easter weekend with just one point gained from six, the Spireites now have seven games to confirm their Sky Bet League 1 future.
Sitting two points above the drop zone, Chesterfield welcome a Port Vale side eight points shy of the play-off places and in need of a win themselves to set up a any sort of a late top-six assault.

After international excursions Connor Dimaio has returned and is ready for squad contention, whle on-loan left-back Declan John prematurely returned to Cardiff City with a hamstring injury that keeps him out of Saturday's game.
Manager Danny Wilson has said that otherwise his squad has come through unscathed from the hectic Easter weekend, with Dion Donohue also in the frame for a return after missing the last three games with suspension.
With Jake Orrell making his first Football League appearance on Monday at Oldham and the likes of Jordan Slew and Rai Simons banging in goals in the reserves, Wilson hopes for such players to be able to soon make the step-up to the first team
Port Vale will be without Ryan Inniss after the on-loan Crystal Palace defender pulled a hamstring, Inniss likely to miss the remainder of the campaign.
Better news for the former Spireites player and now Vale manager Rob Page is that his leading scorer, Ajay Leitch-Smith, came through the full 90 minutes in the side's last match after his hamstring injury.
Chesterfield's difficult Easter double-header means the Spireites have now gone four games without a win, a stutter that needs to be averted soon to improve the survival chances.
Vale have suffered a similar recent blip in their play-off pursuit, with two defeats and a draw in their last three outings, the latest of which was a 1-0 home defeat to Barnsley - who the Spireites play next weekend - on Monday.
Saturday's visitors have recorded five away wins this term and the corresponding fixture at Vale Park in the snow earlier this season saw the hosts come out on top in a 3-2 Vale win.
From the Dugout
Speaking to PlayerHD in his pre-game press conference Wilson commented that his squad is still training with a high level of confidence.
"Moral is still the same," he said. "They've trained very well since they came back. They know what's expected from them in the remaining games and what we need so from that point of view nothing's changed from the weekend.
"A home game always offers you the chance to get maximum points, albeit against the very tough and disciplined team that we'll be up against.
"That said, the belief is still the same, we still believe we can go out and get maximum points."
With visiting manager Page stating this week that his side hold little hope of a late play-off surge, Wilson said that he's sure Vale still feel they can make a challenge.
He said: "I don't believe for a moment that they've got nothing to play for, so it'll be tough. I don't believe that he thinks they don't have a chance if they win tomorrow.
"From their point of view, with 18 points to play for that table could change very quickly. They won't come to the Proact with any thoughts other than to win the game and be very positive.
"More importantly it's not about Port Vale getting into the top six, it's about us getting away from the bottom four and that's what our approach will be."
