However, Brazilian medical staff have suggested that Anderson's injury is not thought to be too serious although he is unlikely to be fit in time for Brazil's Under 23 game on Sunday.
"Anderson felt an injury to his knee, a twist," said Brazil team doctor Jose Luiz Runco.
"However, it doesn't seem so serious. We will be sure only after the MRI scans.
"Only after the scans will we be able to make a decision about Anderson's participation in Sunday's match."
