Unbeaten Chiefs take early lead over Oakland

OAKLAND, Calif. -- Trent Green passed for 199 yards and scored on a 2-yard run, and the unbeaten Kansas City Chiefs knocked league MVP Rich Gannon out of the game while taking a 10-0 lead over the Oakland Raiders after three quarters Monday night.

Priest Holmes of the Chiefs rushed for 98 yards, but defense ruled in a meeting of archrivals with a history dating to the AFL. Kansas City stayed comfortably in control during the first 45 minutes at the hostile Coliseum despite scoring just one touchdown from 292 total yards of offense.

The Kansas City defense pounded Gannon and held Oakland's pathetic offense to 114 total yards in the first three quarters. Seldom-used backup Marques Tuiasosopo started the second half in place of the ineffective Gannon, who had a bruised right shoulder after the last of several crushing hits.

After falling to 2-4 with consecutive road losses in the previous two weeks, the slumping Raiders were hoping the game wouldn't signal a shift in power atop the AFC West. But Kansas City controlled the first three quarters while aiming toward its seventh straight victory.

The Raiders lived up to their promise to keep the ball away from dangerous kick returner Dante Hall, but that strategy hurt them midway through the first quarter. Stranded deep in his own territory, Shane Lechler punted directly toward the Oakland sideline, giving Kansas City the ball at the Raiders 44.

Moments later, Eddie Kennison slipped underneath two defenders and hauled in Green's 43-yard pass at the 1 despite safety Derrick Gibson's interference on the play. Green sneaked around the right end two plays later.

Kansas City had a 55-yard drive late in the second quarter, leading to Morten Andersen's 37-yard field goal with 1:07 left. Otherwise, Oakland's defense had reasonable success against the Chiefs' powerful offense.

But the Raiders' offense remained perplexingly stagnant despite the return of Jerry Porter, the No. 3 receiver who played a key role in Oakland's run to the Super Bowl last season.

Oakland finally mounted a significant drive in the final seconds of the first quarter, but Eric Warfield intercepted a pass intended for Tim Brown inside the Kansas City 20.

Porter was back in uniform for the first time since the season opener after missing five games following hernia surgery. He caught a 10-yard pass over the middle late in the second quarter.

The catch kept alive Oakland's best drive of the half, but it ended when Vonnie Holliday batted down Gannon's pass on fourth-and-1 at the Kansas City 26.

Gannon was 10-of-19 for 58 yards and an interception before leaving the field holding his shoulder -- courtesy of a hard hit by Shawn Barber -- on the Raiders' final offensive play of the first half.

After throwing just six passes all season, Tuiasosopo was no more effective than Gannon, who stood on the sidelines with his helmet on in the third quarter before receiving treatment on the sideline. Dexter McCleon intercepted Tuiasosopo late in the third quarter, killing another drive in Kansas City territory.

The Chiefs won their first six games for the first time in franchise history, but coach Dick Vermeil hasn't been happy with his defense's play -- though three strong quarters against Oakland should help to change his mind.

Oakland's quarterbacks constantly were in harm's way when protection broke down on an injury-plagued offensive line with injuries to three projected starters. Making matters worse, starting tackle Langston Walker left midway through the first quarter with an apparent injury to his right knee.

The Chiefs got much better weather than in their previous trip to Oakland, when the Raiders ground out a 24-0 victory in a pouring rain last December.
