Additionally, the family maintains that they "will continue to support the National Football League and its recent on-field rule changes and procedures to make the game Frank loved so dearly—and the players he advocated so tirelessly for—as safe as possible."
NFL commissioner Roger Goodell issued a statement to ET on Wednesday in response to the Gifford family. "We appreciate the Gifford family's desire to help the medical community understand more about CTE, and we are grateful for their support of the league's efforts to improve safety in our game," he said. "At the NFL, we are supporting grants to NIH and Boston University as well as other independent efforts to research the effects of repetitive head trauma."
"But we are not waiting until science provides all of the answers. We are working now to improve the safety of our game," Goodell's statement continued. "The NFL has made numerous rules changes to the game, all to enhance player health and safety at all levels of football."
