Perfection slips away: K.C. is last team to lose

STEELERS 19, CHIEFS 13

KANSAS CITY, MO.» Le’Veon Bell ran for 179 yards and a touchdown, Antonio Brown made an acrobatic touchdown catch in the fourth quarter and the Pittsburgh Steelers held on to beat the Kansas City Chiefs 19-13 on Sunday.

The Chiefs (5-1) still had a chance after Brown’s 51-yard reception made it 19-10, moving quickly downfield and getting a 33-yard field goal from Harrison Butker.

And when their defense forced a quick three-and-out, Tyreek Hill’s 32yard punt return gave them the ball with 1:48 to go.

But after the Steelers (4-2) gave up a first down, James Harrison sacked Alex Smith on third-and-10, and the quarterback’s incomplete pass on fourth down left the NFL with no unbeaten teams.

Ben Roethlisberger was 17-of-25 for 252 yards for Pittsburgh, bouncing back from his abysmal five-interception performance against Jacksonville the previous weekend.

His favorite target was Brown, who a few weeks ago was flipping over water coolers on the sideline but spent Sunday slinging high-fives.

Brown finished with eight catches for 155 yards, often beating all-pro cornerback Marcus Peters.

The game in many ways resembled January’s divisional playoff game at Arrowhead Stadium, when Bell churned for 170 yards rushing and the Steelers’ defense shut down the Chiefs in an 1816 victory.
