The wild AFC West race is going down to the final weekend.

Jon Kitna threw two touchdown passes in the first half and the Seattle Seahawks moved into a tie for the division lead with a 23-14 victory over the Kansas City Chiefs today.

"That was a great one," first-year Seahawks coach Mike Holmgren said. "We had to have it."

The Seahawks (9-6) broke their four-game losing streak and also ended the Chiefs' four-game winning streak.

If Seattle wins its regular season finale against the Jets next Sunday in New York, the Seahawks will win the AFC West.

"This is good," Kitna said. "But it's nothing if we don't win next week."

That would put them in the playoffs for the first time since 1988, regardless of how the Chiefs (9-6) do in their wrap-up game at home against Oakland. Seattle beat Kansas City twice this season.

"Our backs are against the wall now," Kansas City tight end Tony Gonzalez said. "Their backs were against the wall today and they came out and played a good game."

Elvis Grbac threw three interceptions for Kansas City, which entered today's game leading the NFL by a wide margin with a plus-23 turnover differential.

Chris Canty intercepted Grbac in a scoreless final quarter, when the Seahawks had to play without workhorse running back, Ricky Watters, who was lost because of a right knee injury.

Seattle's Todd Peterson kicked field goals of 48 and 22 yards in the third quarter, and Grbac found Joe Horn behind the secondary for a 76-yard touchdown pass.

The Seahawks had to settle for Peterson's 22-yarder after Shawn Springs intercepted a pass and returned it 27 yards to the Kansas City 6. A penalty against Cris Dishman for illegal use of the hands put the ball on the Chiefs 4, but the Seahawks had to kick a field goal four plays later.

The game was the regular season finale for the Kingdome, which will be torn down after the season to make way for a new outdoor football stadium. But the Seahawks would host a playoff game if they beat the Jets.

Kitna was 18 for 30 for 216 yards and two touchdowns, and Grbac was 21 for 40 for 250 yards and two touchdowns.
