There has been a lot of controversy recently, surrounding professional sports and head injuries.
Specifically the NFL.
The suicide of Junior Seau was just one of many tragedies thought to have been brought on by head trauma.
A new documentary is coming out about all sports, from youth to pro, and their relationship with head injuries.
There's a culture of toughness that keeps many people from disclosing to others or even learning themselves of how badly injured they are.
Check out the video (above) to see the official trailer for Head Games!
