Paris St-Germain forward Neymar has undergone a "successful" operation after fracturing a metatarsal and spraining an ankle during Sunday's Ligue 1 victory over Marseille.
A club statement said Neymar will begin rehabilitation before being "assessed in six weeks' time". Brazil team doctor Rodrigo Lasmar said the 26-year-old is believed to be out for up to three months.
He expects Neymar to be fit in time for the World Cup in June.
But the £200m world record signing will miss the rest of PSG's season.
PSG coach Unai Emery initially said Neymar had a "small chance" of facing Real Madrid in the Champions League next week, before Neymar's father said he would be out for "six to eight weeks". Lasmar, in quotes reported by O Globo,said: "The operation will be in Belo Horizonte on Saturday morning, and the recovery takes from two and a half months to three months. "Neymar is sad, but understands he has no alternative now. He will devote himself to being well as soon as possible".
