Better ban soccer too. At young ages soccer is even worse than football for per capita head injuries.
Source please. More knee injuries, maybe. Not head injuries.
I have also read that more head injuries occur in soccer. Most from heading the ball and missing.
Comparing the Two Sports Both sports carry a risk of injury, and it is impossible to quantify an individual player's overall risk of injury during a game of a season. In general, both sports take a relatively heavy toll on the knees and lower extremities. The risk of injury to the upper extremities is much higher in football than in soccer -- with the exception of the goalkeeper, soccer players do not use their hands and arms to handle the ball. However, concussion injuries are equally likely in soccer and football players. Football players are more likely to suffer injuries to the cervical spine, which can be catastrophic or life-threatening.
