In recent years a lot of attention has been focused on the health risks that N.F.L. players face, especially with concussions and brain injuries, but the range of health problems that current and former players experience are far more extensive.
Now the union representing N.F.L. players has chosen Harvard University to lead a $100 million study to research, treat, and eventually attempt to limit and prevent injuries and other long-term health complications for its members.
Dr. Lee Nadler is co-director of the study and dean for clinical and translational research at Harvard Medical School. Dr. Nadler says the the aim of the study is to evaluate the "true health, of the whole player, in their whole life."
