We begin with professional football on the toll it takes on athletes. We're talking about concussions. Today a victory for the players over the NFL. It's about money and responsibility. And ABC's Jim Avila starts us off. Reporter: Football heroes crushed by the violence of the sport they love.

Nobody makes a gift of hundreds of millions of dollars, unless they believe they are implicated in the wrongdoing in some respect. Reporter: The damage done by repeated brain injury dramatically illustrated on capitol hill today in a video made by Utecht, the former colt and bengal pass receiver.

Reporter: A father of three who testified his memory loss and fears of isolation caused by dementia began after suffering five concussions over a short five-year NFL career.
