Randy Moss found his way back to familiar turf, celebrating a touchdown at Lambeau Field in his new uniform.
The San Francisco 49ers defense kept Aaron Rodgers and the Green Bay Packers out of the end zone for most of the day -- then made sure they didn't give the game away.
Showing the same brand of dominant defense that powered them to the NFC Championship Game last season, the 49ers smothered Rodgers and the Packers offense, then made one last stand to stop a late rally in a 30-22 victory on Sunday.
49ers linebacker Ahmad Brooks said the 49ers' win could be an "eye opener" for the Packers, and a sign that the 49ers are poised for another big playoff run.
"Maybe we'll see them again in the NFC Championship," Brooks said.
Facing a Packers team that lost only once in the 2011 regular season was a tough opening road test, but the 49ers were more than ready.
"We were just tremendously on it today, and that was a big part of our victory," 49ers coach Jim Harbaugh said.
Things went so well for San Francisco that when David Akers tried a 63-yard field goal at the end of the first half, it bounced off the crossbar and then kept going through the uprights to tie an NFL record.
"When you hit the goal post at any part it usually makes that horrific noise and then it usually bounces back," Akers said. "This time it got there. It was a sweet bounce. It was definitely a once-in-a-lifetime type of a deal."
Alex Smith picked apart the Packers. He was 20 of 26 for 211 yards and two touchdowns, and Frank Gore rushed for 112 yards and a touchdown.
Moss scored on a 14-yard reception in the second quarter. He then turned his back to the crowd and pointed to the name on his jersey, opting for a more subdued celebration than the now-notorious fake mooning motion he made toward fans at Lambeau during his Minnesota Vikings days.
