The NFL and NHL are more concerned with getting players back onto the field or ice as quickly as possible. Their concern is that the owners are paying good money for players who suit the bench. Even the NCAA does not take a long term view of head injury.

For example, The NFL has established over 80G's as the threshold of impact forces to the brain before they consider a player sidelined. They claim that since most impact forces are for micro-seconds, that they do not justify concern for the player's brain health.

The NFL Players Association led by Gene Upshaw has been at odds with disabled players because those with head injuries are getting overlooked by the association for disability issues.

Try to get a soccer coach to acknowledge that heading the ball can cause long term damage. They will not. But the science says it does and has been saying this for decades.

There is a Congressman from Massachusetts (Congressmen Ed Markey (MA-7) and Bill Pascrell (NJ-8)) that has been fighting for the brain injured for years but has been been stymied by the insurance industry and others who do not want to have to pay out for brain injuries. His focus has been brain injuries from roller coasters. The BIAA has testified at the Blue Ribbon Panel Hearings but it appears that the threshold for what a brain injury is has been set too high.

There is a Bill before Congress right now. There is a good article at http://www.startribune.com/sports/vikings/11702386.html
