Neymar's father expects his son to miss "between six to eight weeks" and ruled out any chance of playing against Real Madrid next week, he told ESPN Brasil on Tuesday night.

The Brazilian star suffered a crack in the fifth metatarsal of his right foot and sprained his ankle during Paris Saint-Germain's 3-0 win over Marseille on Sunday, but coach Unai Emery insisted earlier on Tuesday that no decision has been made over whether Neymar will have surgery.

However, Neymar Sr, who serves as his son's agent and manager, told ESPN that a quick return is out of the question, despite PSG's hopes that their star player will recover in time for next week's crucial Champions League clash against Real Madrid.

"PSG already know they will not have Neymar in the next few games, six weeks minimum, because this treatment will last six to eight weeks," Neymar Sr said. "That is already certain, regardless of surgery. What we can't do is something that may cause a fracture in the future."

He added: "Yes, of course he is out against Real Madrid. It is absurd if anybody thinks otherwise."

Neymar Sr also said that PSG and his son are both waiting for Brazil's medical staff to arrive to decide about whether to have surgery, but he was positive that the injury was of the kind that would call for an operation.

"We are waiting on PSG to settle this, where [surgery] will happen, it is not up to Neymar to decide," Neymar Sr said. "It is not my decision, or his. I'm not a doctor, our family doesn't have any doctors.
