Changes are coming to the NFL's concussion protocol, after the way an injury to the Dolphins quarterback was handled. A big hit in a Sunday game in week 3 left Tua Tagovailoa wobbly. He was evaluated for a head injury but allowed back into the game by a team trainer and independent neuro-trauma consultant. Just days four later, he suffered another big hit and serious concussion in a Thursday night matchup. The injury reignited a national debate over concussions, and how best to protect athletes in contact sports. The league has since promised it will take action. Earlier this week, former WWE wrestler and neuroscientist Dr. Chris Nowinski joined host Lisa Brady to discuss the Tagovailoa injuries, his concerns over the dangerous long-term impacts of concussions, and what he sees as the NFL's failure of leadership to protect the players' health. Dr. Chris Nowinski, who has his own concussion history and is still coping with lingering impacts, also discussed the need for not only reform pro-sports but also children's sports. He explained how his 'Stop hitting kids in the head' campaign is intended to end harmful practices for youth in contact sports including discouraging kids from playing tackle football until they're 14. Due to time limitations, we could not include all of the conversations in our original segment. On the FOX News Rundown Extra, you will hear our entire conversation with former WWE wrestler and neuroscientist Dr. Chris Nowinski and hear more of his unique take on the NFL's concussion policies, the research going in to head injuries, and why his own personal struggles after past concussions have motivated him to fight for major changes.
