Gillingham manager Andy Hessenthaler is without two key players for the visit of Chesterfield.
Striker Dennis Oli and defender Tony Sinclair have both been ruled out of the game at Priestfield.
Oli limped off in the Gills' midweek reserve game with a recurrence of a niggling hamstring injury and is unavailable, while scans have shown Sinclair has broken a seasmoid bone on his right foot and is likely to be occupying the sidelines for around four to six weeks.
Hessenthaler also has a doubt over striker Adebayo Akinfenwa who has been struggling with a groin problem and as a result missed training on Thursday, but some good news for the Gills is that Joe Martin has been passed fit for the visit of John Sheridan's side.
Top scorer Craig Davies looks like losing his battle to be fit for the trip.
The 14-goal striker is still struggling with a hamstring problem so the Boxing Day visit of Bradford will be his next target for a return.
However Dean Morgan, who played for over an hour and scored twice in the midweek Derbyshire FA Senior Cup victory against Evo-Stik Premier side Mickleover Sports, looks ready to return after a groin injury.
Defender Jamie Lowry completed the full 90 minutes in that game to move closer to a return to first-team contention after 14 months out with a knee injury. He could be on the bench at the Priestfield.
Ian Morris and Rob Page also got a run out to help get them back to match fitness, while fellow defender Jack Hunt looks to be over his bout of illness.
