Kansas City's Jamaal Charles rushed for 92 yards and a TD and had a 13-yard scoring reception, but also lost two fumbles, including one at his own 5-yard line to set up Battle's first score and a 17-0 lead in the first quarter. Chiefs quarterback Matt Cassel was 24-of-42 for 251 yards with two TDs and three interceptions.
