For Week 3’s “Sunday Night Football” matchup, the (1-1) Atlanta Falcons host the (2-0) Kansas City Chiefs at Mercedes-Benz Stadium. Both teams are coming off emotional 1-point victories in Week 2. The Chiefs needed a 51-yard Harrison Butker field goal as time expired to hand the Cincinnati Bengals a 26-25 loss last Sunday afternoon, while the Falcons took a 22-21 lead over the Philadelphia Eagles with less than 40 seconds remaining on “Monday Night Football” — and then sealed the win by intercepting Philadelphia quarterback Jalen Hurts on the next drive.
