Nick Lowery kicked four field goals and Gary Green blocked a punt that was recovered for a touchdown today as the Chiefs beat the Chargers, 19-12, in Kansas City's first victory over San Diego since 1978.

"We feel like they have the best passing offense in the NFL, and we think we're the best secondary," cornerback Green said. "We met them head on, and we did it."

The Chargers, who trailed, 16-0, at halftime, were hurt by poor play, turnovers and penalties. The game left both AFC West rivals at 1-1, and in two games the Chiefs' offense still has not scored a touchdown and the San Diego defense still has not allowed one.

The tone of the day was set on the first series when all-pro Green went over the left side and leaped high to block Maury Buford's punt on the 25-yard line. The ball was batted and bounced around until Dave Klug recovered in the end zone for a touchdown.

Lowery, who had three field goals in the Chiefs' opener, had three in the second period. The Chargers got their first score early in the third period when Chuck Muncie threw a 17-yard scoring pass to Wes Chandler. Later in the period, the Chargers got two points when officials called Matt Herkenhoff for a chop block in the end zone, scoring a safety.

Two breakdowns in the San Diego kicking game, a fumble by Dan Fouts and a drive that consumed more than nine minutes gave the Chiefs their halftime lead.
