The chairman of the National Football League’s health and safety advisory commission believes American football could ban helmets in the future.
The NFL has tried to reduce the risk of head injuries over the last five years and recently reached an almost $1bn legal settlement with ex-players suffering with head trauma.
But some experts think helmets give the players a false sense of security.
“Can I see a time without helmets? Yes,” said Dr John York.
“It’s not around the corner, but I can see it.”
