Under continued pressure from fans, parents and lawmakers to address the growing problem of head trauma in football, the N.F.L. will spend another $100 million on the development of new technology and more research on the effects of head injuries.
The initiative, announced by Commissioner Roger Goodell in an open letter on Wednesday, comes on top of more than $100 million the league has spent on new equipment and long-term studies on the impact of concussions and repeated head hits.
This time, the league said the money would be earmarked for “independent medical research and engineering advancements” to increase the “prevention, diagnosis and treatment of head injuries, enhance medical protocols and further improve the way the game is taught and played by all who love it.
