Linvoy Primus is expected to be passed fit for Charlton's home game against Ipswich on Saturday.
The on-loan Portsmouth centre-half suffered a back injury during Tuesday night's defeat at south London rivals Crystal Palace, but he has had a painkilling injection and should be available.
Should Primus miss out, England under-21 defender Martin Cranie could move across from right-back, with Jose Semedo or Yassin Moutaouakil coming in.
Under-pressure boss Alan Pardew has promised changes following the Selhurst Park defeat so Andy Gray should reclaim his place in attack alongside Luke Varney.
Svetoslav Todorov, Chris Dickson, Zheng Zhi, Jonjo Shelvey and Grant Basey will also push to be involved.
Jonathan Fortune (knee), Therry Racon (foot) and Harry Arter (Achilles) are still out but striker Izale McLeod (knee) has been pencilled in for a reserve game next week.
Ipswich manager Jim Magilton is set to name an unchanged squad for the trip after the morale-boosting win over Barnsley in midweek.
Magilton made three changes for the win over the Tykes and saw two players who came into the side - midfielders Owen Garvan and Ivan Campo - score.
The manager must now decide whether to name the same XI away from home but may revert to playing Jon Stead on his own up front with Tommy Miller and David Norris both hoping for recalls in midfield.
Defender Ben Thatcher will miss out on a return to one of his former clubs as he is out with a torn thigh muscle.
Moritz Volz is still struggling with his hamstring problem and is unlikely to feature while fellow defender Pim Balkestein is also unlikely to make the trip as he has a groin injury.
