After German player Christoph Kramer took a hit to the head and fell to the ground, World Cup fans could see that something wasn’t right, yet team doctors cleared him to continue playing. Kramer fell again without even being touched just 15 minutes later, spurring the debate on head injuries that were ignored in the World Cup this year.

As a former BMX rider who was forced to retire due to multiple concussions, Fraga’s personal story will leave you a lot to think about.
