Neymar will spend a period on the sidelines after suffering a cracked metatarsal during PSG's 3-0 Ligue 1 victory over rival Marseille on Monday (AEDT).
The world's most expensive footballer, having arrived from Barcelona in a blockbuster deal worth close to $350 million last August, will miss the return leg of PSG's UEFA Champions League Round of 16 showdown against holder Real Madrid.
But Neymar remains upbeat, the 26-year-old Brazil international using a quote made famous by six-time NBA champion and Chicago Bulls icon Michael Jordan as a source of inspiration.
"Obstacles should not stop you. If you find a wall, do not give up. Discover how to climb it," Neymar wrote on Instagram, with an accompanying photo of him injured on the field against Marseille at Parc des Princes.
Neymar, who has been linked with a sensational switch to Spanish and European champion Madrid, has flourished at PSG.
The Brazilian has scored 28 goals across all competitions for the French giant this season.
Meanwhile, PSG president Nasser Al-Khelaifi said he is hopeful Neymar will be fit for the UEFA Champions League quarter-finals, should Unai Emery's side overturn a 2-1 deficit.
"It was the best decision for Neymar and the club, and it was a decision made by the player himself, the club and Brazil. We didn't have the choice, we decided to operate," he said after PSG's 3-0 win over Marseille in the last eight of the Coupe de France on Thursday (AEDT).
Al-Khelaifi added: "We could not take the risk of delaying the operation. We do not want to waste time, so we hope he will be ready for the quarter-finals of the [UEFA] Champions League."
