Neymar has suffered several serious sprains of his right ankle in recent years.
After the latest incident on February 20, a 4-3 win over Lille, when Neymar was carried off in tears on a stretcher, PSG's medical team have recommended he undergo ankle ligament surgery to prevent the risk of a recurrence.
During the World Cup in Qatar, Neymar was forced to sit out two matches due to pain in the same ankle.
All the experts consulted agree on the necessity of the operation.
It will be three to four months before he can be back in training with the team.
