The defending AFC champions are squaring off with one of the remaining undefeated teams in the NFL.  The Bengals host the Dolphins for a Thursday night showdown in Cincinnati.  Cincinnati earned its first win of the season in Week Three after beating the Jets 27-12.  Joe Burrow threw for three touchdowns in the victory, but the Bengals are still struggling to find success in the run game.  Meanwhile, Miami is the lone undefeated team in the AFC at 3-and-oh.  The Dolphins proved their merit with a 21-19 win over the Bills and Tua Tagovailoa [[ TUNG-oh-vai-LO-uh ]] continues to impress under center.  The QB did suffer an ankle and back injury against Buffalo and is officially listed questionable to play.
