Charlton are monitoring the fitness of leading scorer Lyle Taylor ahead of the visit of Birmingham.
The in-form striker picked up a knock on international duty with Montserrat and Addicks boss Lee Bowyer will see how he fares over the coming days before making a decision on his availability.
On-loan midfielder Beram Kayal could be in contention for a Charlton debut after making two substitute appearances for Israel over the international break.
In a further boost for Bowyer, Deji Oshilaja has returned to training after picking up a knock against Brentford last month, while fellow defender Adam Matthews is also closing in on full fitness.
Birmingham forward Kerim Mrabti could make his first-team return for the trip to The Valley.
Mrabti had a hamstring injury and has not featured since the opening game of the season, but was on the bench for his side’s 2-1 win over Stoke on August 31.
The Blues will be without winger Jefferson Montero for several weeks after he sustained a thigh injury against the Potters.
Bernard Sun could be included in the squad after signing as a free agent on a two-year contract earlier this month.
