Beevers ruled out of Gills clash
The defender missed Saturday's home defeat by Leeds with a shoulder injury and is not fit to return, so Alan Maybury is likely to stay at right-back.
Centre-back Paul Reid is edging closer to a comeback following knee surgery but will not be available at Priestfield, while strikers Steven Gillespie (hamstring) and Jamie Guy (knee) are still missing.
Clive Platt returned from a ban on the bench on Saturday and could be handed a start.
Mark Cousins, Joel Thomas, Anthony Wordsworth and Matt Lockwood may also be in the starting line-up if caretaker boss Joe Dunne opts to make changes in what should be his final game in charge - the U's hope to name a new manager on Wednesday.
