Frontline: League of Denial - The NFL's Concussion Crisis

An examination of the NFL's response to football-inflicted concussions, including its attempts to refute scientific evidence linking on-field collisions to early-onset dementia and brain damage. The report details the case of former Pittsburgh Steeler center Mike Webster (1952-2002), whose chronic traumatic encephalopathy was likely caused by football; and also looks at the health risks of high-school and college football. Based on Mark Fainaru-Wada and Steve Fainaru's book, "League of Denial."
