Johnnie Jackson is in line for an immediate debut when Charlton host Yeovil.
Jackson has joined the Addicks on a month's loan from Notts County to be reunited with manager Phil Parkinson, who once signed him for Colchester.
The former Tottenham trainee is a midfielder by trade, but he can also play at left-back which is where he will fill in against the Glovers.
Parkinson swooped for Jackson after the injury suffered by Grant Basey against Bristol Rovers last Monday. Charlton initially feared the youngster had broken his leg but scans have showed up ankle ligament damage instead.
With Kelly Youga still missing with a knee injury Parkinson had no left-sided alternative until Jackson arrived.
Elsewhere, striker David Mooney will shake off a head injury and youngster Jonjo Shelvey is pushing for a recall.
Yeovil will wait on the fitness of central midfielder Jean-Paul Kalala.
Kalala, who has recently completed a two-match suspension, was ruled out of Tuesday's 1-0 home defeat by Colchester through illness.
Gavin Tomlin (illness) was also sidelined but both are expected to be back in contention by Saturday.
Glovers boss Terry Skiverton will be without winger Ryan Mason (knee) through injury.
Mason also missed Tuesday night's defeat.
His place in Yeovil's starting XI against Colchester went to new on-loan Brighton winger Arron Davies, enjoying a second spell with the Huish Park club.
