KANSAS CITY, Mo. — The Falcons gladly took advantage of a short-handed Chiefs defense Sunday. Matt Ryan threw for 299 yards and three touchdowns, one of them to tight end Tony Gonzalez in his return to Kansas City, and Atlanta used a second-half surge to pull away for a 40-24 victory. Ryan also ran for a TD, and Julio Jones caught six passes for 108 yards and two scores, both of them enjoying a Chiefs defense missing four starters due to injuries and suspension.
