KANSAS CITY, Mo. — Ryan Succop kicked a 41-yard field goal to give the Kansas City Chiefs a 3-0 lead over the Pittsburgh Steelers after the first quarter Sunday night.

The Steelers nearly answered with a touchdown on their opening possession, driving inside the Chiefs 10-yard line. But backup running back Mewelde Moore had the ball poked out by Chiefs linebacker Tamba Hali and it was recovered by Javier Arenas in the end zone for a touchback.

Kansas City gave the ball right back when Tyler Palko, making his second career start for injured quarterback Matt Cassel, fumbled the snap. The Chiefs' defense managed to hold Pittsburgh, but Palko gave the ball away again when he threw an interception on the final play of the first quarter.

It was the fourth pick thrown by Palko in five quarters — he had three last week at New England.

Steelers quarterback Ben Roethlisberger, playing with a fractured thumb on his throwing hand, was 6 of 8 for 82 yards in the first quarter. Palko was 5 of 7 for 51 yards.
