Kansas City, Mo. ? Kansas City defensive back Ty Law said he might lose a little sleep over his gaffes against the Seattle Seahawks.

Rest easy, Ty.

Larry Johnson, Damon Huard and Tony Gonzalez were watching out for you.

Law nearly squandered a dazzling performance by the Chiefs’ offense in a 35-28 victory over Seattle on Sunday, when the Pro Bowl cornerback dropped a sure interception and two plays later was burned on a 49-yard touchdown pass from Seneca Wallace to Darrell Jackson.

The touchdown, which gave the Seahawks a 28-27 lead with 6:30 to go in the game, came a few minutes after holder Dustin Colquitt bobbled the snap on a field-goal attempt. Seattle defensive back Kelly Herndon picked it up and raced 61 yards for another Seahawks touchdown.

“We gave up a couple of big plays on defense that kept them in the game. That’s why it was so close,” Law said.

“It was one of those days for me,” he added. “Normally I catch that pass and run down the sideline. It wouldn’t be just an interception, I have plenty of those. But it would have been a sure-shot touchdown. I’m going to lose a little sleep over that one.”

Johnson rushed for 155 yards and had four touchdowns, the last one capping an 80-yard drive that bailed out Law and Colquitt and gave the Chiefs (4-3) a 35-28 lead with 2:15 to go.

The bruising back’s 39 carries set a franchise record, wearing down a Seattle defense that was on the field for more than 42 minutes.

“Larry is All-Pro, and let’s get serious, they’ve got two All-Pro linemen in front of him,” said Seattle linebacker Lofa Tatupu. “Anytime you can’t stop the run, it is going to be a long day for us.”

Huard, whose status wasn’t decided until game-time because of a sore groin muscle, completed 17 of 25 passes for 312 yards and a touchdown, repeatedly finding holes in Seattle’s zone defense. He improved to 4-2 as a starter, but coach Herm Edwards said another solid performance by the longtime backup won’t make a difference when injured quarterback Trent Green is ready to return in a couple of weeks.

“I can’t say enough about Damon Huard,” Edwards said. “He was a little nicked up and got through the game. That’s what we anticipated, and he did a great job of going back and making some throws. I think our players rallied around him.”

Much of Huard’s success was in finding Gonzalez running down the seam. The Pro Bowl tight end had six catches for 116 yards, twice setting up Kansas City touchdowns with long catches.

“They forgot Tony can catch and run with the ball,” Johnson said. “That helps us. It takes a big chunk out of their confidence and gets the ball up the field.”

Wallace, making his first NFL start in place of injured Pro Bowl quarterback Matt Hasselbeck, was 15-for-30 for 198 yards, with three touchdowns and two interceptions.

He didn’t have a glaring mistake until the final minute, when the Seahawks (4-3) had the ball on fourth-and-15 at the Kansas City 46-yard line. Rather than throwing down field, Wallace threw an outlet pass to his fullback, who came up well short of the first down.

“In that situation, we’ve got to take the shot down the field to try and get something,” Seattle coach Mike Holmgren said. “I can’t be too hard on him. I think that he battled. The outcome of the game, in a negative fashion, wasn’t because of Seneca Wallace.”

It might have been because of injuries and suspensions, though.

Besides Hasselbeck, the Seahawks offense was missing MVP running back Shaun Alexander, wide receiver Bobby Engram, starting guard Floyd Womack and right tackle Sean Locklear, who was suspended this week for violating the NFL’s personal-conduct policy.
