Contrast scientific findings that suggest a link between football-related head injuries and brain disease with the NFL’s own statements and actions in this timeline of the NFL’s concussion crisis from the FRONTLINE: League of Denial website. The dual chronology runs from 1994, when the NFL created a committee focused on mild traumatic brain injury, through 2013, when the league agreed to settle a lawsuit brought by retired players that accused the NFL of having concealed information regarding football’s dangers to their brains. For background on CTE, a progressive, degenerative brain disease linked to concussions and milder brain injuries, watch Introduction to CTE and review How CTE Affects the Brain.
