The NFL is hosting a seminar that's aimed at improving and discussing the NFL's efforts at reducing the amount of concussions around the league.
Speaking to a group of roughly 300 people, Goodell said the focus of the seminar was one part of a larger movement towards overall player safety.
The NFL has two new co-chairs of the NFL Medical Committee on Head, Neck and Spine -- Dr. Richard Ellenbogen and Dr. Hunt Batjer -- who are formulating plans to make the game safer starting at the youth level.
"They will schedule their meetings and timelines and decide when information is ready to be made public," Goodell said of the co-chairs. "We are supporting them and giving them full independence and transparency to do their work. And they would not have it any other way."
Medical reps from all 32 NFL teams are in attendance.
