Spireites travel to Cheltenham Town tomorrow, a ground on which they have never conceded a goal.
Robins’ were in the play-off zone as recently as January but their midweek game at home to bottom club Stockport ended a nine game winless run that has seen them fall to 12th spot.
Star man in Mark Yates’ side is 18 goal nippy striker Wes Thomas. Exactly who is detailed to marshal him will be dependent on whether Ian Breckin manages to shake off the virus that kept him out of the midweek win over Wycombe.
John Sheridan went into that game without a recognised central defender, full backs Dean Holden and Gregor Robertson stepped in to the breach and did well and may have to hold the fort again.
On the injury front, the manager said: “Mark Allott (ankle) and Dwayne Mattis (calf) are coming along well, whether Saturday is a bit early, we’ll see, but they’re both running and getting fitter. Simon Ford (calf) is just behind them but I hope to have them all fit quickly because they add strength to the squad.”
Jack Lester is likely to be rested with Dean Morgan set to play up front with Ian Morris favourite to return to midfield.
Sheridan added: “It’s another big game, a tough game but we’re just trying to win as many games as possible and win them as quickly as possible, so we’ll try and win at Cheltenham and then at home to Northampton after that. They’re all tough games, no matter who you play.”
Northampton sacked manager Ian Sampson this week after a run of seven without a win. Malcolm Crosby has been put in temporary charge.
