Michael Vick and Peyton Manning gave the fans what they wanted in the American Bowl, playing into the second quarter and showing why they are two of the NFL's best quarterbacks.

Vick displayed some of his trademark scrambling in the preseason opener yesterday, gaining 10 yards on his only run in the Atlanta Falcons' 27-21 win over the Indianapolis Colts in Tokyo.

He went 4 for 7 for 51 yards before a Tokyo Dome crowd of 45,203.

"I wanted to give the fans something to cheer about," said Vick, who left after the first play of the second quarter. "Just wanted to get the jitters out, and I didn't want to shortchange the fans or myself."

Better yet, he didn't get hurt.

"Michael had a good game," Atlanta Coach Jim Mora said. "I was holding my breath when Mike was running the ball. In fact, I just let my breath out now."

Manning threw a two-yard touchdown pass to Troy Walters with 6 minutes 45 seconds left in the first quarter, giving the Colts a 7-0 lead. He was 6 for 8 for 36 yards with one interception.

Vick's replacement, Matt Schaub, threw two touchdown passes in the first half and was the game's MVP. Schaub completed 11 of 13 passes for 115 yards.

* RAIDERS: Rich Gannon officially called it quits, retiring from the Oakland Raiders after missing most of last season with a broken vertebra in his neck.

The 39-year-old quarterback, supported by about a dozen teammates and several coaches, announced his decision at the team's training facility in Napa, Calif. It had been expected for months.

"As far as the decision to retire, it was an easy one for me," Gannon said, sitting alongside team owner Al Davis and Coach Norv Turner. "It really was not my decision. I was not able to continue to play physically."

Gannon, the 2002 NFL MVP, already has signed with CBS Sports as an NFL game analyst after playing 18 seasons in the league.

* TEXANS: Houston gave running back Domanick Davis a new five-year deal and a big raise, scrapping his league-minimum contract after two straight 1,000-yard rushing seasons.

Davis was in the last year of a three-year contract that paid him $360,000 annually. While financial terms of the new contract were not released, General Manager Charley Casserly said Davis was getting a substantial raise.
