PSG boss Unai Emery has said both players are unlikely to make it this weekend due to injury concerns, but the duo are set to be fit for the Champions League tie against Anderlecht on October 18.
Silva was injured while on international duty with Brazil, while Kurzuwa also suffered a knock while in action for France over the international break.
Emery told his press conference: "Thiago spent the morning at the training centre. His injury is not thought to be too severe but he might not be in the squad for Saturday's match."
On Kurzuwa, he added: "He has done some running," he said. "We believe he will be ready for the Champions League match."
Javier Pastore, however, has recovered from his calf injury and may be back in the squad.
