Charlton have a host of injury problems ahead of the FA Cup visit of Huddersfield.
Centre-half Leon Cort and full-back Lawrie Wilson are the latest additions to the casualty list.
Cort suffered a hamstring injury during the 4-3 win over Watford on New Year's Day and Wilson came off with a broken nose.
Striker Danny Haynes is out with a hamstring problem and defender Rhoys Wiggins (foot) is still sidelined along with midfielders Andy Hughes (Achilles) and Ade Azeez (hamstring).
In addition loanees Dan Seabourne, Rob Hulse and Emmanuel Frimpong have now returned to their parent clubs.
But centre-half Michael Morrison returns to the squad after missing out at Vicarage Road through suspension after he was sent off against Derby.
Jermaine Beckford is expected to return to spearhead Huddersfield's attack.
The on-loan Leicester striker was ineligible to play against his parent club in the Terriers' 6-1 mauling at the King Power Stadium on New Year's Day, but has been cleared to play in the cup, as has fellow forward James Vaughan, who is on loan from Norwich.
Winger Adam Hammill, due to return to parent club Wolves on January 13, has not been given permission to play.
Manager Simon Grayson is hoping goalkeeper Alex Smithies can overcome the dead-leg that prompted his withdrawal at Leicester, but if not Ian Bennett will continue to deputise.
Defender Calum Woods (groin) and winger Danny Ward (knee), who have missed the last two and three matches respectively, are both in a race against the clock to be fit, while midfielder Oscar Gobern continues his rehabilitation following ankle surgery.
