GREEN BAY, Wis. (AP) -- The New York Giants left Brett Favre and

the Green Bay Packers wobbly.

Tiki Barber rushed for 182 yards and scored on a 52-yard

touchdown run, and Kurt Warner threw a touchdown pass to Jeremy

Shockey in a 14-7 victory Sunday at Lambeau Field, where Favre was

knocked from the game with a concussion.

The Giants improved to 3-1 despite a series of missed

opportunities, including three errant field goal attempts by Steve

Christie.

"This was a phenomenal win for us," defensive end Michael

Strahan said. "Our rate of improvement has been quicker than I

expected."

And the rate of Green Bay's descent has been equally surprising.

The Packers, mired in a mess with cornerback Mike McKenzie and

trying to overcome infighting and injuries, fell to 1-3 for the

first time since 1993 and have their first three-game losing streak

under fifth-year coach Mike Sherman.

Favre sustained a concussion when defensive lineman William

Joseph knocked him to the ground in the third quarter and missed

the next two plays. Favre went back in on fourth-and-5, waved

backup Doug Pederson to the sideline and floated a 28-yard

touchdown pass to Javon Walker for a 7-0 lead.

"I wasn't surprised that he came back in and threw a touchdown

pass like he did," Strahan said.

The Packers' medical staff sure was -- they hadn't cleared Favre

to return to action.

Sherman said he turned to Favre and asked if he was OK. Favre

said yes, so in he went.

"The doctors told me after that they didn't want him back in

the ballgame," Sherman said.

So, Favre was done for the day.

And soon the Packers were, too.

"Brett Favre is Brett Favre," Giants cornerback Terry Cousin

said. "We couldn't underestimate Doug Pederson. He's a good

quarterback who's been in the league a long time. But only Brett

Favre can make some of those throws and make something out of

nothing. That's the difference between him and everybody else."

Favre, who extended his NFL quarterbacks record to 212 straight

starts, counting playoffs, didn't speak to reporters afterward.

Several teammates said they doubted his starting streak was in

jeopardy.

Warner said that when they spoke on the field afterward, Favre

was fuzzy.

"I talked to him just for a minute to see how he was feeling.

He didn't remember the touchdown play," Warner said. "You knew he

wasn't quite right."

Two plays after Favre's TD, Barber beat the blitz with a 52-yard

touchdown run to tie it at 7.

"We had to strike right away," said Barber, who carried 23

times. "Rarely do you get a run like that. It takes good blocking

and luck."

Warner appeared to have made a costly mistake when he did a hook

slide 18 inches shy of the goal line, but Shockey juked cornerback

Michael Hawthorne and grabbed a 4-yard TD pass on third-and-goal to

give New York a 14-7 lead with 12 minutes left.

"Next time, I'll dive head first," Warner said.

Pederson hurt his side on a hit near the sideline but stayed in

until the final play, when third-stringer Craig Nall threw a

24-yard pass to Robert Ferguson to the Giants 32. But the clock

expired before he could spike the ball and take a shot at the end

zone.

The Packers have been a team in turmoil and are now in full

crisis management.

McKenzie was deactivated for the second straight game with a

mysterious hamstring injury. He wasn't on the sideline Sunday even

though the other injured players all were. Sherman said he came in

for treatment only.

Since ending his holdout without retracting his trade request

three weeks ago, McKenzie has been paid more than $485,000 but has

played just nine snaps, all against Chicago, leading fans to wonder

whether he's still holding out but getting paid anyway.

Neither team did much offensively in a scoreless first half, the

first time since Oct. 6, 1980, that the teams had gone into their

locker rooms at Lambeau Field without any points.
