Brazil will wait 24-to-48 hours for a full assessment of the injury Neymar suffered during its 2-0 victory over Serbia on Thursday.

The team doctor described the forward's issue as a "trauma" to the right ankle, according to The Independent's Miguel Delaney. Neymar appeared to be in tears after he was substituted during his country's World Cup opener.

The 30-year-old seemed to pick up the injury when Nikola Milenkovic challenged him during a counterattack.
