According to multiple sources, the Miami Dolphins placed Tua Tagovailoa on injured reserve after he sustained another concussion in a recent game against the Buffalo Bills, his third documented concussion in his NFL career. Under league rules, Tagovailoa will miss at least four games as he focuses on recovery. In response, the Dolphins signed quarterback Tyler Huntley from the Ravens’ practice squad to strengthen their depth. Skylar Thompson will start in Tagovailoa’s absence, with Huntley serving as backup.
