Quarterback Alex Smith was 21 of 32 for 251 yards passing and a touchdown as the Kansas City Chiefs defeated the Pittsburgh Steelers, 23-13, at Arrowhead Stadium in Kansas City, Mo.

Charcandrick West added 110 yards rushing with a touchdown on 22 carries as the Chiefs head into their London trip with a victory. It was West's first 100-yard rushing day of his career, and the first by a Kansas City running back this season.

The first half of the game was largely a defensive struggle that saw a combined five field goal attempts. Chiefs kicker Cairo Santos was 3 for 4 and Steelers K Chris Boswell was 1 for 1, and at the half, Kansas City led Pittsburgh, 9-3.

The Chiefs and Steelers exchanged punts in the second half until a major defensive play by safety Eric Berry.

On first-and-10 from the Kansas City 49-yard line, Steelers quarterback Landry Jones tried to find wide receiver Antonio Brown, but the ball hit Brown and bounced up in the air. Berry dove for the ball and picked it off for his first interception since December of 2013. 

Off the interception, the Chiefs scored their first touchdown of the game thanks to a 1-yard run by West.

The Steelers answered back on the ensuing possession with a 19-yard touchdown from Jones to WR Martavis Bryant for Bryant's third touchdown in the past 2 games.

At the end of three quarters, it was 16-10 Chiefs.

The Steelers added another field goal in the fourth to make it 16-13, but the Chiefs offense padded the lead with another score. Smith connected with rookie WR Chris Conley for his first touchdown of his career, a 6-yard strike that made it 23-13.

Berry led the Chiefs in total tackles with 6. Linebacker Derrick Johnson had his first interception of the year. LB Tamba Hali had two sacks and a forced fumble.

With WR Jeremy Maclin ruled inactive for the game, tight end Travis Kelce led the Chiefs in yards receiving with 73. WR Albert Wilson had 3 receptions for 71 yards.

In his first career start, Steelers QB Landry Jones went 16 for 29 for 209 yards passing, 1 touchdown and 2 interceptions.

With the win, the Chiefs improve to 2-5, snapping a five-game losing streak. Kansas City travels to London next week to meet the Detroit Lions at 8:30 a.m. CT.
