Ian Breckin could return to the Chesterfield squad when the run-away league leaders host Northampton.
The experienced centre-half missed the victories against Wycombe and Cheltenham through illness. However, a makeshift defence, with Scott Griffiths at centre-half and Derek Niven at full-back, impressed in both matches.
Boss John Sheridan made only one change from the 4-1 win over Wycombe, with Kieran Djilali coming into the team at Cheltenham in place of Jack Lester.
Sheridan`s policy of playing Lester in Chesterfield`s games at the b2net Stadium is likely to see the veteran striker return to the starting XI.
Mark Allott made his return from an ankle injury as a late substitute during the 3-0 win at Cheltenham and the midfielder could be included once more.
New Northampton manager Gary Johnson will be without striker Billy McKay.
McKay dislocated his elbow during the 3-2 defeat to Shrewsbury on Saturday and is beginning an absence which could run into several weeks.
Fellow frontman Leon McKenzie is also out with his nagging knee injury so captain Andy Holt could again be asked to fill in up front. Former Coventry duo Marcus Hall and Kevin Thornton missed out at the weekend through illness but took part in Johnson`s first training session on Monday morning.
Goalkeeper Steve Collis, right-back Seth Nana Ofori-Twumasi and left-back Jamie Reckord are all in contention after joining the Cobblers on loan on Monday.
Defender Craig Hinton has had an injection in a long-standing knee injury and will be out for around a month.
Midfielder Ryan Gilligan has returned from his loan at Torquay a week early after suffering a family bereavement but cannot play until the Macclesfield game on March 12.
