Neymar will return to Paris in around two to three weeks, according to head coach Unai Emery.
Neymar was reportedly a possible doubt for the World Cup as a result of the injury, with the 26-year-old also sustaining an ankle sprain.
But Emery believes Neymar is closing in on a return to the pitch, although Saturday's Coupe de la Ligue final against Monaco will come too soon.
"I talked to him this week," Emery told reporters on Friday.
"He's okay, quiet, we were talking about the final.
"He'll be watching it and then he'll be back [in Paris] in two or three weeks."
