Dolphins place Tua Tagovailoa on injured reserve after latest concussion

The Miami Dolphins are placing Tua Tagovailoa on injured reserve after the quarterback was diagnosed with his third concussion in two years, a person familiar with the move told The Associated Press on Tuesday.

The person spoke on condition of anonymity because the team had not yet announced the move. Tagovailoa will be sidelined for at least four games with the designation.

He was hurt in the third quarter of a Thursday night game against the Buffalo Bills on a play where he collided with Bills defensive back Damar Hamlin. He ran for a first down and then initiated the contact by lowering his shoulder into Hamlin instead of sliding.

Players from both teams immediately motioned that Tagovailoa was hurt, and as he lay on the turf the quarterback exhibited some signs typically associated with a traumatic brain injury. He remained down on the field for a couple of minutes, got to his feet and walked to the sideline.

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.
