Dolphins quarterback Tua Tagovailoa returned last week after being evaluated for a concussion. He started in Thursday Night Football despite back and ankle injuries.
But his night ended early with a scary injury.
Tagovailoa was sacked for a 10-yard loss by Josh Tupou with 5:57 remaining in the first half. The back of his helmet bounced off the turf in Cincinnati.
He was placed on a stabilizing board before being loaded onto a stretcher.
Amazon showed repeated images of a “fencing response” in Tagovailoa’s hands, which is a neurological response to head trauma.
The entire Dolphins team walked to midfield out of concern for Tagovailoa.
Tagovailoa was 8-of-14 for 110 yards and an interception.
Teddy Bridgewater has replaced Tagovailoa.
