It seems to me that the worst thing that can happen to Neymar is that he will have to miss a couple of games, this is a minor injury and should not lead to more significant consequences. Brazil already have 3 points and in the remaining two games of the group stage they need to win at least once - this is an easy task given that their opponents are not so strong, so there is no danger that the absence of Neymar will be important. And to be honest, I think Brazil, even without Neymar, will score 7 or 9 points in the group.
Its a matter of sorrow for the Brazil fans. Last Thursday Brazilian duo Neymar and Danilo suffered injuries during the game against Serbia. Due to which they will miss the rest of the group matches. Brazil will play two matches against Switzerland and Cameroon in which both of them will not be able to play.
According to the doctor, "Neymar and Danilo went through a MRI on Friday afternoon and found ligament damage in both of their ankles. Doctors said that they will certainly miss the next matches. But the doctors are trying so hard so that they can come back to the World Cup again.
