Neymar, the world's most expensive footballer, was stretchered off 10 minutes from time at the Parc des Princes as PSG opened up a 14-point lead in Ligue 1.
Neymar was pictured at a nightclub in the Paris suburbs attending a private concert held by the American rapper Tyga.
A tearful Neymar pleaded with the media to stop false stories about his alleged frosty relations with PSG coach Unai.
Neymar called for an end to 'false stories' about his alleged frosty relations with Paris Saint-Germain coach Unai Emery and striker Edinson Cavani.
Neymar was not only harried and niggled by a series of fouls in the game, but also pelted by Stade Velodrome fans with coins.
Unai Emery believes it reflects well on his team that Europe's traditional powerhouses now see PSG as enemies.
The capital-city side have seen their early lead at the top of the table cut to one point this weekend after reigning champions Monaco thumped Lille on Friday.
