Tua Tagovailoa is in the training room to be evaluated for a head injury.
The Dolphins quarterback leapt into the air on an 8-yard pass to Jaylen Waddle on third-and-three at the Miami 21. While in the air, Bills linebacker Matt Milano pushed him back.
The back of Tagovailoa’s helmet bounces violently on the ground.
He tried to get up and was obviously dazed, with two of his offensive linemen rushing in to help steady him.
The team medical staff helped him head straight to the training hall without stopping at the medical tent. The Dolphins classify him as doubtful to return.
The Bills were penalized 15 yards for Milano manhandling the passer’s penalty.
Teddy Bridgewater replaced Tagovailoa.
The Dolphins also lost right tackle Greg Little to what appears to be a hand injury. Larnel Coleman replaced Little.
