Green Bay Packers Coach Lindy Infante has been searching for a weakness in the San Francisco 49ers, and his hunt will likely continue through kickoff Sunday.

The teams meet for the first time since last November, when the Packers beat the 49ers 21-17. San Francisco, 7-0, has since won 15 straight games, including Super Bowl XXIV."It's kind of hard to find chinks in a 7-0 armor," Infante said. "If there is, it's a little nick here and there someplace. You don't have big holes and come out 7-0 or 15-0 or whatever they are since we played them last."

Infante downplays last year's victory and is hoping for the same the type of performance this season from the Packers, 3-4.

"The only thing we did that nobody else did was we got more points in that particular football game," Infante said. "We went out there and played one of our better games last year. That's what you have to do if you expect to beat the world champs. They're very talented, they're very well put together and they're certainly playing with great confidence."

Green Bay may catch San Francisco at the right time this season. The 49ers and quarterback Joe Montana have struggled on offense the past two weeks. Montana has thrown for a total of 342 yards, two touchdowns and four interceptions. The ground game has 267 yards in the same period.

"There are some things we have to evaluate," 49ers Coach George Seifert said. "The last two teams have done a good job of defensing some of the things we do, and maybe we have to look at what we're doing to see if we're tipping by formation, or down and distance, or whatever."

San Francisco should be bolstered by the return of running back Roger Craig and wide receiver John Taylor, both who have been sidelined with injuries.

"They've got all the pieces in place," Infante said. "They've been together for a long time and they go out there and figure out ways to win. If anybody's going to beat them, you've got to go out there and figure out a better way to win than they do."

In other games Sunday, it's Chicago at Tampa Bay, Washington at Detroit, New Orleans at Cincinnati, Buffalo at Cleveland, Atlanta at Pittsburgh, Dallas at the New York Jets, New England at Philadelphia, Houston at the Los Angeles Rams, Miami at Phoenix, the Los Angeles Raiders at Kansas City, and San Diego at Seattle.

Denver plays Minnesota Sunday night and the New York Giants visit Indianapolis Monday night.

At Tampa, Fla., the Buccaneers are 3-0 in NFC Central games but have lost their last two overall entering Sunday's game against the division-leading Bears. They committed 12 turnovers in those two losses.

"We've still got eight games left and we know we can't make the kinds of mistakes we've made the last few weeks," said Tampa Bay's Vinny Testaverde, the NFL's second-rated passer who will return to the lineup after missing one game with a toe injury. "The toe feels good now and I don't expect any problems with it Sunday.

"Everybody's pretty confident, but we're a little frustrated with the way things have gone this year."

At Minneapolis, the Vikings and Broncos will try to get their kinks worked out and get back on the right track.

Minnesota heads into the game with a dismal 1-6 record, while Denver has a 3-4 mark. Both teams are struggling in all phases of their games.

At Indianapolis, the Giants put their 7-0 mark on the line. They join the 49ers as the NFL's only unbeaten clubs.
