Real coach Jose Mourinho had already said on Saturday that former World Player of the Year Kaka would have to wait a little longer before making his return to international football with Brazil as he was nursing a calf injury.
"The players are prevented from playing due to muscular injuries, as confirmed by scans sent by Real Madrid to the Brazilian national team's medical department," the CBF said on its website.
It added that Bayern Munich midfielder Luiz Gustavo would miss Thursday's match in Gabon because he had not obtained proof of vaccination needed to enter the African country and would only be available to play against Egypt in Qatar.
"He wouldn't have time to recover. It's an injury that has nothing to do with the serious problems of the past," Mourinho said. "It's a small injury typical of those that happen every season and he's going to stay here 15 days to recover."
