The field goal capped a 13-point fourth quarter for Kansas City. It was set up by a 78-yard reception by Larry Johnson -- and a face-mask penalty against Cardinals' tackle Antrel Rolle that sent Johnson out of the game with a neck injury.
Quarterback Damon Huard was 26-of-38 for 288 yards and two touchdowns, and Johnson finished with six catches for 106 yards and a score for the Chiefs (2-2), who have won two straight.
Leinart, in his first NFL start, completed 22-of-35 passes for 253 yards, two touchdowns and one interception, and Edgerrin James rushed for 71 yards on 24 carries for the Cardinals (1-4), who have lost four straight.
