Defender Gregor Robertson and midfielder Jimmy Juan are outside chances to make the squad for the Boxing Day trip to Huddersfield Town.
Robertson, aged 27, has had a few thigh problems since recovering from a long term achilles injury.
The former Rotherham United man, generally a left back, switched to centre half last season and took to the position well.
With conceding goals being Spireites’ problem this term, the Scot gives manager John Sheridan an option in the troublesome position that so far this season has seen nine different pairings. Juan is just short of match practice having been unattached since the summer.
He’s played three reserves games for Chesterfield so could be considered ready and, should Sheridan choose to pack his midfield, he looks to be a decent shout for a start.
Striker Jack Lester will serve the first of his three-match ban at the Galpharm Stadium after the club decided not to appeal his violent conduct charge in relation to an incident which occured against Walsall last weekend.
Terriers boss Lee Clark has just two men on the treatment table, keeper Alex Smithies (knee) and midfielder Damien Johnson (hamstring), but he’ll be without skipper Peter Clarke.
The central defender will be suspended after picking up his fifth booking of the season in the 4-4 draw at Hillsborough last Saturday.
Former Chesterfield loan players Jack Hunt and Donal McDermott could both feature for Huddersfield.
