Josh Gowling is unlikely to be fit for Gillingham's home npower League Two match with Oxford.
Gowling is struggling and manager Andy Hessenthaler is likely to call upon Garry Richards - who replaced the central defender in midweek - should he fail to recover.
While the Gowling news is a blow, Gillingham have also received several boosts on the injury front.
Tony Sinclair is scheduled to resume full training on Monday after a foot complaint, while Andy Barcham trained for the first time on Thursday following an ankle injury.
Dennis Oli returned to action in the midweek draw with Stevenage after a two-month absence with an ankle problem and is in contention for a start after coming off the bench.
Luke Rooney and Curtis Weston, who were also substitutes at the Lamex Stadium, are pushing for starts.
Damien Batt will miss out for Oxford through suspension.
The 26-year-old received a straight red card 66 minutes into Tuesday evening's 2-1 defeat at Southend for a hefty challenge on midfielder Anthony Grant.
Batt will therefore miss the Gills clash as he starts a three-game ban, meaning Ben Purkiss is likely to replace him at right-back.
Purkiss has impressed since joining from York in the summer and is likely to be given a starting berth at Priestfield.
Batt's ban is the only concern for manager Chris Wilder as there are no other fresh suspension or injury worries.
