Humphreys is still recovering from Saturday's game at Morecambe, with Spireites boss Paul Cook telling the media during this pre-match press conference that he is without any fit full-backs, with Drew Talbot absent again and Nathan Smith (ankle) still out.
Fellow defender Matty Brown (hamstring) and strikers Marc Richards and Armand Gnanduillet are also still out. Richards (thigh) is expected to be out for "a few weeks", while Gnanduillet is set to have his knee injury scanned.
Gary Roberts is still suspended after his red card in the league meeting between the two sides nine days ago.
