Midfielder Ajdarevic and goalkeeper Thuram-Ulien recently joined the Addicks on loan from Standard Liege but were not signed in time to play in the FA Cup draw against Oxford on Tuesday night.
Striker Smith was cup-tied in midweek having returned from a successful loan spell at AFC Wimbledon.
Right-back Chris Solly could return after he was rested against Oxford, midfielder Dale Stephens (illness) will be checked over while defender Leon Cort (knee) and striker Marvin Sordell (hamstring) are out.
