Brazil's football federation has revealed that Manchester City striker Gabriel Jesus sustained a broken eye socket during Friday's 1-0 friendly defeat to Argentina.
Gabriel was taken off the field on a stretcher late in the game after being hit by a stray elbow during an aerial challenge with club teammate Nicolas Otamendi.
He was initially given the all-clear after precautionary tests but the CBF later said that, after a more detailed examination, a fracture was diagnosed in the bone that protects his left eye.
Brazil will not call up a replacement for Tuesday's friendly with Australia, also in Melbourne.
