Brazil's leading goal scorer is suffering from a thigh injury. His leg is swollen and coach Luis Felipe Scolari is preparing for the reality that Neymar won't be fit in time for Friday's match.
Neymar suffered the injury early in Brazil's match against Chile. Although he played the full match and scored the deciding penalty, Neymar was hobbled for good portions.
Neymar is tied for second in World Cup scoring with four goals.
