Brazil coach Luiz Felipe Scolari says losing Barcelona star Neymar for the rest of the World Cup is a "catastrophe".
Neymar was ruled out of the tournament last Friday when he was hit in the lower back during an aerial challenge with Colombia defender Juan Zuniga.
"It's equivalent to a catastrophe," the Brazil coach said of losing his star man.
"Neymar is out reference. He is a player that would make the difference in any team.
"We have lost the one player we did not want to lose, and it's for the semi-final and final."
The Brazilian federation (CBF) confirmed on Sunday that team psychologist Regina Brandao would visit Teresopolis.
Scolari found the ordeal of seeing his best player injured hard to take.
"It was a big shock," he said. "The image of Neymar being carried off a stretcher towards the plane, the difficulties, the tears..."
