After suffering a series of brutal concussions between 2010 and 2012, former Indianapolis Colts wide receiver Austin Collie became a poster child for the league's head trauma crisis. Now, he has walked away from football in order to take a job as a care coordinator and director of business development for a concussion clinic in Utah.
The following is a first-person story from Collie documenting his experience with concussions, his education in the field of traumatic brain injuries and his quest to help fellow former and current athletes better deal with the recovery process, as told to Bleacher Report's Brad Gagnon.
