PSG forward, Neymar, could be set for some time out after suffering an injury on his left thigh during the friendly against Nigeria in Singapore.
The Brazilian forward limped out of the Selecao's 1-1 draw against the West Africans after just 12 minutes and was replaced by Philippe Coutinho.
After he was subbed off, the 27-year-old was pictured icing the injury, which suggested that he might miss the next games for the Parisians.
The Ligue 1 champions travel to Nice on Friday to face Patrick's Vieira men as they seek to maintain their top spot in the French top-flight.
Neymar had already missed a few PSG games through suspension while he resolved his future at the start of this season. But he was in fine form for them when he returned, scoring four times in five games.
The former Santos man who became the youngest man to reach 100 caps for Brazil against Senegal on Thursday will likely require tests to assess the severity of his current injury.
