Nice try. He's a neuroscientist.
"Christopher John Nowinski is an American neuroscientist and author. Co-founder and CEO of the Concussion Legacy Foundation, and co-founder of the Boston University CTE Center, he is also a former professional wrestler with World Wrestling Entertainment."
He's also a professional wrestler and not a medical doctor. He also did not diagnose or even talk to Tua.
Unless something comes out that shows the Dolphins hid something, whatever you try to post is not going to change the fact that tests by actual medical doctors at the game and after the game, including independent tests all showed no concussion and the NFL and NFLPA are satisfied that there was no concussion.
