Charlton will be without winger Dennis Rommedahl and striker Marcus Bent for Saturday's FA Cup fourth round visit of Orient.
Rommedahl will be sidelined for another week after cracking a rib in Sunday's 1-1 draw at Chelsea. Bent is cup-tied, having played for Everton in the third round.
Midfielders Danny Murphy and Alexei Smertin could be back in contention after time on the sidelines.
Provisional squad: Myhre, Young, Hreidarsson, Fortune, Powell, Ambrose, Holland, Kishishev, Hughes, Murphy, D Bent, Bartlett, Spector, Perry, Andersen, Thomas, Smertin, Bothroyd.
