Until Aaron Rodgers found a seam for his lone touchdown pass and a couple of other deep throws, the Ravens defense had the Packers' star quarterback shut down.
Rodgers was limited to 116 passing yards while being sacked three times and forced to fumble twice in the first half alone.
Perhaps it was the amount of time the defense was forced to stay on the field because of the offense's eight three-and-outs, but the unit seemed to tire in the end. After holding Green Bay to 163 yards and six points in the first half, the Ravens finished with 438 yards and 19 points allowed. It was the most yards surrendered by Baltimore since giving up 501 to Denver in the opener.
Linebacker Elvis Dumervil, who had two sacks and two forced fumbles, liked the overall performance.
"If we don't win, it's just a great effort," Dumervil said. "I thought our guys, we fought hard, we did what we had to do. But we have to do it for four quarters and try to get the W."
James Ihedigbo, Terrell Suggs and Daryl Smith led the Ravens with 10 tackles apiece. Art Jones added a sack.
The Baltimore D continued its strong play at home, permitting just one touchdown and four field goals to Green Bay, which had been averaging 29.5 points per contest.
The Ravens have now surrendered just one touchdown in three home games this season, averaging 11.3 points against at M&T Bank Stadium.
But Baltimore couldn't completely shut down Rodgers. He ended with 315 passing yards, a touchdown and a Jimmy Smith interception.
"He's a good quarterback. No, he's a phenomenal quarterback. We knew that going in," Suggs said. "We wanted to limit the plays he could make. (Dumervil) made some great plays out there, but Rodgers did a good job identifying where to go with the football. I tip my hat to him. He played one hell of a game."
It didn't help Baltimore that Rodgers had a running game on his side. Eddie Lacy ran for 120 yards, becoming the third Green Bay back to reach the century mark this season.
"We've been trying to get the defense to start fast. But he popped one early, and they stayed with it," Suggs said of Lacy. "In the NFL, you stay with your running game, especially on the road. If you have a good running game on the road, you have a good chance to win."
The Packers did just that, and now it's time for Steelers week.
