Broward Health Medical Center's chief of neurosurgery weighed in Friday on the growing concerns over Miami Dolphins quarterback Tua Tagovailoa's long-term health after he sustained a concussion - his third while playing in the NFL.
Christopher Roberts, both a fan and a doctor, recounted watching Tagovailoa suffer one of his injuries in Thursday night's Dolphins-Bills game.
As a fan, he thought, "not again," but as a neurosurgeon, Roberts quickly noticed tell-tale signs of trauma, including a posture known as the "fencing response," often seen in concussions.
"Anytime you strike your head like that and you have that maneuver with the hands - it's just concerning, You know right away something is wrong," said Roberts. "A clenching of the arms sometimes it can be a flexing of the arms and its just when the brain has lost control of the body."
