Neymar will not require surgery on his injured right ankle and should be fit again within four weeks.
Neymar suffered a severe sprain of the outer lateral ligament playing a friendly against Qatar on Wednesday night, ruling him out of the upcoming Copa America tournament.
Paris Saint-Germain said in a statement on Saturday that two of the club's doctors evaluated Neymar's injury and decided it will heal without an operation.
The 27-year-old Neymar also injured the fifth metatarsal in his right foot this season and last.
Wednesday's match in Brasilia was his first major public appearance since a woman accused him of rape at a Paris hotel on May 15.
Neymar has denied any wrongdoing.
