The NFL has reached a $765 million settlement in a concussion lawsuit with 4,500 litigants.

The NFL will fund medical exams, concussion-related compensation and a program of medical research.

Many former NFL players have suffered a wide-range of head trauma related health effects.

U.S. District Judge Layn Phillips was the appointed mediator to help broker a settlement.

There is a dismissal of liability moving forward, while players will receive 50 percent of compensation over the next three years and the rest over the next 17 years.
