Tagovailoa was ruled out with head and neck injuries and taken to a local Cincinnati hospital for further tests. The Dolphins announced that he has movement in all of his extremities.🏈Miami #Dolphins QB Tua Tagovailoa left the TNF game on stretcher after appearing to suffer a head injury. @ProFootballDoc gives his immediate analysis 👇👇👇Full video⏩ https://t.co/SN9wkYe2tX pic.twitter.com/9taHNppjbD— Sports Injury Central (@SICscore) September 30, 2022 The 24-year-old didn't appear to suffer any neck or spine injuries on the sack, according to the Pro Football Docs.Consecutive and repeat concussions often require absences of a month or more, but the greater concern is for second impact syndrome, which can develop when someone suffers a second concussion before healing from the first.#Dolphins QB Tua Tagovailoa left the field on a stretcher and is headed to the hospital after this playFull details: https://t.co/PxIfcp8HEG pic.twitter.com/xirQ9NLlTx— Sports Injury Central (@SICscore) September 30, 2022 Tagovailoa suffered a hyperextended back and exhibited outward signs of head trauma in the Dolphins' win four days ago but returned for the second half and missed only one day of practice this week.A litany of former players, reporters, and concussion activists have expressed thoughts on Twitter with how the team handled Tagovailoa's recent head injuries.The NFL reportedly confirmed that the Dolphins followed appropriate concussion protocol last weekend, responding to the NFLPA's request to investigate immediately after Sunday's game.That’s a serious injury .
