Brazil will be without top striker Neymar for the remainder of the World Cup.
He has a broken vertebrae resulting from a collision with Colombia's Juan Zuniga in the 88th minute of Friday's quarter-final.
Neymar will not be available when Brazil face Germany in the semi-final on Tuesday, or for the final on July 13, should Brazil advance.
Team doctor Rodrigo Lasmar says Neymar broke the third vertebra in the lumbar region of his back.
The fracture does not require surgery.
