Laudrup has said that Williams will need to be at full fitness before he is brought back into the team.
"If we are not careful it could become a chronic problem with him. He has not been 100% and that's not good for a player to carry on playing because there are always doubts," Clubcall.com quotes Laudrup as saying.
"And you could go on for months always playing at 85% and we don't want that so it's better to wait.
"We wanted him back for this game against Sunderland but it is more important to get him back 100% so he is comfortable when he is playing."
Williams has made 10 appearances for Swansea this season.
