Miami Dolphins quarterback Tua Tagovailoa has been diagnosed with a concussion after a collision with Bills safety Damar Hamlin during a game on Thursday night. The incident occurred in the third quarter, leading to Tagovailoa lying on the ground for several moments before being assisted off the field. This marks the third concussion for Tagovailoa in his NFL career, following two concussions sustained during the 2022 season. Despite his history of head injuries, he had a productive 2023 season, signing a four-year, $212 million contract extension. Following his departure, backup quarterback Skylar Thompson took over for the Dolphins, who were trailing 31-10 at the time. The severity of Tagovailoa's injury has raised concerns about his future in the league, with calls for him to consider retirement due to his concussion history.
