Miami Dolphins quarterback Tua Tagovailoa suffered his fourth concussion during a game against the Buffalo Bills, exiting the match after a heavy hit from Damar Hamlin. Tagovailoa's injury occurred while scrambling for a first down, leaving the Dolphins trailing 31-10 at the time. He finished the game with three interceptions, contributing to a disappointing 31-10 loss against the Bills, marking Miami's fifth consecutive defeat to their division rivals. Despite discussions about acquiring a backup quarterback, head coach Mike McDaniel stated that Skylar Thompson would be the team's starter in Tagovailoa's absence. The Dolphins, who signed Tagovailoa to a four-year extension worth $212 million in the offseason, will proceed cautiously given his history of head injuries. Tagovailoa's latest concussion adds to concerns about his long-term health and future in the league.
