Ben Dempsey and Josh Davison will make their full league debuts as Charlton take on Swansea City at the Liberty Stadium this evening.
The academy graduates are two of five changes from the side that played Derby County on Monday as Adam Matthews, Jason Pearce and Lyle Taylor return to the starting line-up.
Chris Solly, Naby Sarr, Deji Oshilaja and Alfie Doughty move to the bench while Macauley Bonne misses the game after suffering an injury at Pride Park.
Charlton could line-up in a 4-diamond-2 or a 3-5-2. If the aforementioned then Matthews, Tom Lockyer, Pearce and Ben Purrington would make up the back four in front of Dillon Phillips.
Darren Pratley would hold in midfield with Conor Gallagher and Albie Morgan either side of a diamond and Ben Dempsey behind the front two of Taylor and Davison.
If Lee Bowyer opts for a 3-5-2 then Pratley would drop into defence with Matthews and Purrington moving to wing back.
The Addicks injury-ravaged squad is still without 12 first team players.
Andre Green, who signed for the Addicks this morning, is set to train with his new teammates for the first time tomorrow.
Charlton: Phillips; Matthews, Lockyer, Pearce (C), Purrington; Pratley, Morgan, Gallagher, Dempsey; Taylor, Davison
Substitutes: Maynard-Brewer, Solly, Sarr, Oshilaja, Ledley, Vennings, Doughty
