GREEN BAY, Wis. - The New York Giants legitimized their fast start Sunday by leaving 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 at Lambeau Field, where Favre was knocked from the game with a head injury.
The Giants improved to 3-1 despite a series of missed opportunities, including three errant field goal attempts by Steve Christie.
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.
The Packers had one last chance to avoid the upset when Christie missed from 33 yards with 26 seconds left, but third-string quarterback Craig Nall hit Robert Ferguson at the New York 32 down the middle of the field and the clocked expired before the Packers could spike the ball.
Favre sustained a head injury when defensive lineman William Joseph knocked him to the ground in the third quarter and missed the next two plays. But he ran back on the field, apparently without medical clearance, on fourth-and-5 and waved backup Doug Pederson to the sideline.
Favre then floated a 28-yard touchdown pass to Javon Walker, who plucked the pass out of the air at the 3 between cornerbacks Frank Walker and Terry Cousin, then fought his way across the goal line for a 7-0 lead.
Despite his lobbying on the sideline, however, Favre was done for the day.
The Giants quickly responded with their own score. On second-and-1 at the Giants 48, Barber rumbled for a 52-yard blitz-beating touchdown that tied it at 7. He finished with 23 carries on the day.
Warner appeared to have made a costly mistake when he did a hook slide 18 inches shy of the goal line when he could have just lunged across for the score. 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.
The Packers have been a team in turmoil. 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.
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.
The Giants had three takeaways overall, including Will Peterson's interception just before halftime, and Brent Alexander's recovery of another fumble by Ahman Green, his third in four games. But the Giants failed to capitalize on those when Warner threw into triple coverage on third-and-goal from the 2 and Darren Sharper intercepted it, and Christie was wide right on a 49-yard field goal attempt.
The Packers have lost six of their last 12 home games after going 22-3 in their first 25 games at Lambeau Field under Sherman.
