Stephy Mavididi has returned to Arsenal for treatment on his hamstring injury.
The Gunners forward is still on loan with the Addicks, and is set to play a part in their promotion run-in.
He will spend the next few weeks with his parent club before returning to Charlton to conclude the final stages of his rehabilitation.
Meanwhile, Naby Sarr is in contention to face MK Dons on Saturday. The Addicks defender has been crocked with a hamstring strain and hasn't played since New Year’s Day.
Jason Pearce and long-term absentee Lewis Page featured in an Under-23 game on Monday as they continue to build their fitness.
