The injury has triggered concerns for the player's availability for this year's World Cup.
The Brazilian chose to undergo an operation after breaking his fifth metatarsal against Marseille last weekend, rather than recover in the usual way and play on pain-killing injections.
But despite these initial injury fears, doctors have said Neymar should be available for training two weeks before the tournament begins with all things being well.

Neymar is supposedly hell-bent on making a full recovery from his injury to star for Brazil in Russian Federation, with surgery representing the best possible outcome for his foot in the long run.
The world's most expensive footballer was operated on in Belo Horizonte by the Brazil national team doctor.
However, they are 3-1 down going into the second leg of their Champions League, last 16 tie at home to Real Madrid on Tuesday.
Earlier, Paris newspaper L'Equipe reported that PSG believe Lasmar lied about Neymar's condition.More news: Winter storm kills five people, leaves millions without power in United States
The report said that Neymar was initially found to have suffered a minor fracture at the Marseille game and that PSG were shocked when Lasmar declared it was a serious break requiring longer than expected recuperation time.
"There is absolutely no split, despite what was written".
"Re-education will begin immediately under the direction of a club physiotherapist".
The physician added, however, that he should be in "full form" by the time of the World Cup.More news: Militant, four civilians dead in J&K attack
