Heading a soccer ball must also knock a few screws loose as well.
Hmmm... a ball of air vs. 250 lbs of kinetic mass - that seems about equal!
Actually it is being demonstrated that heading a soccer ball can cause concussions:

Researchers who’ve followed soccer players have seen a close relationship between the amount of heading that a player does and brain abnormalities. There’ve also been studies where researchers compared soccer players to swimmers, and swimmers’ brains look perfectly normal while the soccer players’ brains had abnormalities in their white matter fiber tracts. Nerve cells transmit their messages to other nerve cells by way of their fiber tracts, or axons, and if the brain is violently shaken enough, a person can have disruption of their fiber tracts.
