NFL launches new $100 million concussion initiative

Commissioner Roger Goodell wrote a letter on playsmartplaysafe.com stating that the new program will attempt to "drive progress in 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."

"The NFL has been a leader on health and safety in many ways, and we've made some real strides in recent years," Goodell wrote. "But when it comes to addressing head injuries in our game, I'm not satisfied, and neither are the owners of the NFL's 32 clubs. We can and will do better."
