Ray Rice on his way to 101 yards rushing for Baltimore

The Baltimore Ravens moved to 4-1 on the season with an ugly 9-6 victory over the Chiefs in Kansas City.

Justin Tucker made all three of his field goal attempts for the Ravens, knocking the ball over from 28 yards in the first quarter and from 26 yards and 39 yards in the third quarter.

Ryan Succop replied for the hosts with a second-quarter kick from 30 yards and another from 31 yards in the fourth quarter

Baltimore running back Ray Rice rushed for 101 yards, and quarterback Joe Flacco threw for 187 yards and was picked off once, but the Chiefs turned the ball over four times.

Kansas City passer Matt Cassel threw for 92 yards, was intercepted twice and lost two fumbles before leaving in the fourth quarter with what the Chiefs described as a head injury.

Brady Quinn entered and led Kansas City on a drive that ended with Succop's final field goal, but the Chiefs defence could not get the ball back and Baltimore ran out the clock.

Kansas City - regarded as possible Super Bowl contenders before the season started - slip to 1-4.
