Neymar was withdrawn late in the second half to a standing ovation after he picked up a slight knock but he insists there is nothing to worry about.
"I am fine and ready for the next match, and for every match," he said. "I always think about my family and get inspired to play."
Brazil could secure progression to the semifinals with victory against Mexico in Fortaleza on Wednesday.
