Neymar failed to complete 90 minutes for Brazil in their World Cup opener as he limped off the field late in the second half.
Neymar, who was the subject of nine fouls, was visibly upset as he left the pitch and was seen talking to team doctors as they applied ice to his clearly swollen ankle.
Reports suggest Neymar was in tears on the bench and did not celebrate his team’s victory, instead heading straight down the tunnel with his boot off and his swollen foot still visible.
The Paris Saint-Germain striker has just four days to recover from what local reports have described as a ‘sprain’ if he is to play in Brazil’s next group game against Switzerland, who were beaten by Cameroon on Thursday.
Manager Tite also has to deal with right-back Danilo, who looked to have pulled a muscle but battled on until the end of the game as the boss ran out of substitutions.
