PSG head coach Mauricio Pochettino said he was hopeful that Neymar can be involved in Saturday's Ligue 1 game at home to Nantes.
Neymar returned from international duty with Brazil with a thigh problem.
"Yes, he trained well with the group today. We'll see after the medical meeting today, I'm not 100% sure but I think he can be in the group tomorrow," said Pochettino.
PSG have a 10 point lead at the top of the table, having dropped just four points from 13 games.
Nantes are tenth.
