CALUM Butcher will go straight into Neil Harris’ squad after completing his switch to Millwall on Thursday.
The 25-year-old midfielder played 90 minutes for Burton Albion in their 5-0 defeat to Liverpool in the EFL Cup second round on Tuesday, his third appearance of the season.
Lee Gregory is a doubt with the hip flexor problem that forced him off against Sheffield United last Saturday.
Harris could pair Steve Morison with Aiden O’Brien – who scored in the corresponding fixture between the sides last season – if the Irish forward shows no ill-effects from the knock to the foot he suffered against Nottingham Forest on Tuesday night.
Fred Onyedinma looks set to miss out after limping off in the 44th minute of the same game.
Defenders Shaun Hutchinson and Shaun Cummings are still a month away from returning.
Chesterfield are unbeaten in four at Proact Stadium but there is speculation around the futures of striker Sylvan Ebanks-Blake and midfielder Gboly Ariyibi.
After a controversial summer in which they saw long-standing sponsor HTM Products quit after the signing of Ched Evans, and a fake raffle winner drama that attracted national news headlines, Chesterfield have made a solid start to the season and are fourth in the table on seven points.
Millwall record versus Chesterfield:
Won 16 Drawn 7 Lost 14
Probable Millwall team:
