CBS Sports reported Tagovailoa traveled back to Miami with his team while wearing a neck brace. Initial scans performed at a Cincinnati hospital were negative. The Dolphins said he sustained a concussion, and NFL Network reported Friday that Tagovailoa has entered the league's concussion protocol.
Tagovailoa was sacked by Cincinnati's Josh Tupou and swung to the ground violently with 5:43 remaining in the first half. His head and upper back hit the turf hard and his fingers spasmed in an odd manner. CNN's Dr. Sanjay Gupta, a neurologist, said Friday that the movement of his fingers indicated a neurological issue.
