Is the "beautiful game" causing too many concussions among its athletes, particularly the younger ones? If you're watching the World Cup, you would see how it's possible. Between heading the ball (hitting the ball with your head while it's in the air) and the players smacking heads against each other as they vie to head the ball, sometimes it's a wonder that more injuries don't happen. Head injuries can also occur if a player's head hits the ground or, less frequently, the goal post.
