The Brazilian football confederation says the injury is not serious, adding Neymar left as a precaution and would be back in training tomorrow.
The forward trained with his team-mates in Sochi on Tuesday but hobbled away from the session after only 15 minutes.
He had been playing keep-away with a few other players when he started showing signs of discomfort in his ankle.
Worryingly, it was his right foot that caused him problems. "Since today was only a recovery session for the starters, and he complained about pain, he ended going to rehabilitation".
On Instagram on Monday, Neymar posted a picture of his foot while receiving treatment alongside the message "work hard".
