Neymar Knocked Over By Fan While Training
The incident occurred midway through an open session watched by around 15,000 fans at Arena Amazonia.
In chaotic scenes, scores of fans invaded the pitch and one brought Neymar to ground with a bear hug.
The 24-year-old quickly regained his footing and laughed off the episode with teammates.
Later, he threw his shirt into the stands and climbed the fence to hug fans and sign autographs.
