SAN FRANCISCO (AP) While Terrell Owens wowed his fans with a terrific touchdown, the Kansas City Chiefs kept it conservative - and they won when their backup kicker got a second chance.

Owens, the 49ers' All-Pro receiver, made a spectacular 71-yard touchdown reception - and three hours later, Lawrence Tynes kicked a 29-yard field goal 2:25 into overtime Saturday night to give the Chiefs a 17-14 exhibition victory over San Francisco.

The Chiefs didn't reveal much of their offense in their exhibition opener against a team they'll face in the regular season on Nov. 10. Trent Green and Priest Holmes played just one series - but it was a 66-yard touchdown drive.

"We only showed a little bit of what we can do," Kansas City coach Dick Vermeil said. "What do you say after a preseason game? I'm just glad we kept people healthy and didn't play all 15 minutes of that overtime."

After neither team managed to score in the final 17 minutes of regulation, Reggie Stephens intercepted rookie Brandon Doman's wobbly pass at the 49ers 20.

Tynes, who bounced a 42-yard attempt off the right upright with 1:05 left in regulation, easily made the kick. He's not even expected to make Kansas City's roster, but the Chiefs didn't want to use veteran Morten Andersen.

Kansas City beat San Francisco (0-2) with a solid defensive performance, but the best highlight was provided by Owens, who made a thrilling broken-field run before the game was six minutes old.

After catching a short slant from Jeff Garcia, Owens beat cornerback Ray Crockett around the corner, shoved away Jerome Woods with a vicious stiff-arm, bulled past Eric Warfield and dragged three defenders over the goal line.

"I think everybody is getting more comfortable with each other, and everybody wants to improve on some things from last week," Owens said. "I was just feeling it, and I got in there."

Owens made his second straight Pro Bowl last season after catching 93 passes for 1,412 yards and an NFL-best 16 TDs even while complaining he was underutilized in the 49ers' offense. During the summer, he played briefly with the Adirondack Wildcats of the USBL - but he obviously didn't forget his football moves.

Garcia completed 6 of 9 passes for 118 yards in two series of work. Garrison Hearst rushed for 24 yards, and Kevan Barlow caught three passes for 42 yards.

Green went 4-for-5 for 40 yards and threw a 4-yard TD slant to Dante Hall, who caught eight passes for 64 yards. Holmes had five rushes for 26 yards - 18 on an end run deep into San Francisco territory.

"If you look all the way around, you'll see Eddie (Kennison) had a catch, Johnnie (Morton) had a catch, Priest had a catch," Green said of the Chiefs' opening drive. "That's when we're most effective - when we can spread the ball around and not focus on one or two specific people."

Tight end Jason Dunn made an acrobatic 15-yard reception on a third-down play, drawing cheers from holdout Pro Bowl tight end Tony Gonzalez, who was on the Chiefs' sideline in a possible indication that he's close to signing.

The Chiefs had no intention of showing off a high-flying passing offense against the 49ers' third-stringers, as Steve Spurrier's Washington Redskins did while racking up 434 yards passing in San Francisco's 38-7 exhibition loss in Japan.

Both teams got performances from their backup quarterbacks that were less than impressive, however.

Todd Collins was inconsistent, and 49ers linebacker Jamie Winborn launched him airborne with a crushing hit that knocked off Collins' helmet and appeared to cause a fumble, though officials ruled it an incomplete pass after a review.

Tim Rattay went 10-for-19 for 132 yards, throwing two interceptions in extensive playing time for the 49ers, who hope he'll assert himself as a reliable backup before the regular season.

Rattay led a scoring drive in the third quarter, but otherwise struggled. The 49ers designed a game plan intended to give Rattay more experience with long downfield throws, but he connected on only a few.

"We moved the ball well, but we couldn't punch it in there sometimes," Rattay said.

The Chiefs capitalized on one of Rattay's interceptions for a short TD drive, with Jonathan Quinn hitting Josh Roth with a 5-yard TD pass.

But Rattay hit Cedrick Wilson with a 5-yard scoring pass late in the third quarter, capping a 71-yard drive.
