Brazil could be without striker Hulk against Mexico, as he pulled up with an injury during training.
The Zenit forward limped away after scoring in a game between ranks to receive further treatment.
It seems likely Hulk will not be risked for the next match, a head-to-head at the top of Group A with Mexico on Tuesday.
The hot favourite to replace him is Chelsea star Ramires, who already did well as a substitute in the 3-1 win over Croatia on Friday.
Another alternative is Bernard, who replaced Hulk during the closing stages of the same game.
