The midfielder finally returned to action at Fulham last weekend after being troubled by his knee only to take a knock in the latter stages at Craven Cottage that caused further damage.
"Sean had an operation yesterday and the medical staff have told me he will not be available for two or three months," said Head Coach Jacques at this morning's pre-Charlton press briefing at Spurs Lodge.
"It is bad news for Sean and for the team because he is an important player for us.
"Now we play without Atouba, Edman and Sean and that's a big problem for the team but the other players must play well and it's a chance for them."
Jacques Santini has revealed that Sean Davis will be out for 'two to three months' after knee surgery yesterday.
