Miami Dolphins quarterback Tua Tagovailoa suffered a concussion during a 31-10 loss to the Buffalo Bills, marking the third diagnosed concussion of his career. The injury occurred when he collided with Bills safety Damar Hamlin while scrambling for a first down, causing him to hit his head on the turf. Tagovailoa was able to walk off the field but was ruled out of the game, with backup Skylar Thompson taking over. Dolphins coach Mike McDaniel emphasized the importance of focusing on Tagovailoa's health rather than a timeline for his return, stating that they will evaluate his condition day-by-day. Teammate Austin Jackson expressed his concern for Tagovailoa, acknowledging the emotional toll of witnessing his teammate's struggles with injuries. The Dolphins' next game is on September 22 against the Seattle Seahawks, and Tagovailoa's participation will depend on medical clearance.
