GREEN BAY, Wis. - Charles Woodson wouldn’t let the Green Bay Packers’ season slip away.

The veteran cornerback forced two fumbles and picked off a pass by Tony Romo on the goal line as Green Bay’s defense finally played up to its potential against a big-time opponent, beating the Dallas Cowboys 17-7 on Sunday.

It wasn’t a pretty win for the Packers (5-4), but it might have saved their season after back-to-back demoralizing losses.

“It seemed like guys had a lot of passion out there today for the game,” Woodson said. “Where it came from, I don’t know, but we were happy to have it and got a big win for this team. We’ve got to have that passion every week, and it’s got to show up on the field.”

The Packers sacked Romo five times and allowed the Cowboys to convert only three of 12 third-down chances. It was a momentum-killer for the Cowboys (6-3), who had won four straight.

Dallas also lost starting right tackle Marc Colombo to a broken left fibula.

“Their defense is good, they’ve got a good scheme,” Romo said. “I don’t know how they are normally, but today they definitely got good pressure on the quarterback, slowed our running game and they played good behind it. The secondary, they’ve got good players.”

The defense’s dominant performance bailed out an offense that looked lost in the first half.

Aaron Rodgers rallied the Packers after halftime, scoring on a quarterback sneak and throwing a touchdown pass to tight end Spencer Havner. Afterward, Rodgers acknowledged that players knew fans were writing them off after back-to-back losses to Minnesota and Tampa Bay.

“I think a lot of people were thinking this was going to be the end of our road,” Rodgers said.

Rodgers was 25 of 36 for 189 yards and a touchdown in another rough day, taking four sacks and spending much of the day under pressure.

But he took matters into his own hands to lead the Packers on a 15-play, 80-yard drive capped by a 1-yard sneak for a 10-0 lead early in the fourth quarter.

“I’m proud of the fact that when we needed a big drive in the third quarter, we came up with it,” Rodgers said.

Rodgers converted two third-and-long situations against a thin secondary on the drive, as Cowboys coach Wade Phillips said Dallas lost cornerback Mike Jenkins to a left arm contusion, safety Ken Hamlin to an ankle injury and cornerback Alan Ball to a leg injury.

Cornerback Orlando Scandrick committed a pair of penalties on the drive.

“Most of our secondary went out in that one drive, which really hampered us,” Phillips said. “We didn’t have enough DBs to play even a nickel defense.”
