Miami Dolphins quarterback to a Tagovialoa who took a hit about three weeks ago during the team's matchup against the Buffalo Bills. He began stumbling while coming off the field and everyone watching immediately knew something was wrong, but returned for the second half after medical evaluation. Despite what appeared to be clear signs of cognitive impairment, he was greenlit to go back into the game four days later. The league has made some major changes that could impact the sport and one doctor has already been fired.
