Tua Tagovailoa sustained sickening neck and head injuries during the Miami Dolphins ' 27-15 defeat against the Cincinnati Bengals on Thursday.
The quarterback was stretchered off in visible distress after being hit by a crunching tackle from Bengals player Josh Tupou. Upon hitting the deck, Tagovailoa's arms appeared to go into the fencing response, an unnatural position after a concussion.
He needed prolonged treatment from medical staff before going off on a stretcher and heading to hospital at the University of Cincinnati Medical Center. The 24-year-old was discharged laster in the evening and flew home to Miami with the rest of the team.
