The Dolphins placed Tua Tagovailoa on injured reserve Tuesday after the quarterback was diagnosed with his third concussion in two years.

Tagovailoa will be sidelined for at least four games with the designation.

The 26-year-old quarterback was hurt in the third quarter of Thursday night’s game against the Bills on a play in which he collided with defensive back Damar Hamlin. He ran for a first down and then initiated the contact by lowering his shoulder into Hamlin instead of sliding.

Tagovailoa this week began the process of consulting neurologists about his health. He was diagnosed with two concussions in 2022 and one while in college at Alabama.

Tomlin praised Fields for his decision-making and his demeanor but stopped short of saying Fields would be the full-time starter whenever Wilson is cleared to play. ...
