Carolina's second drive generated some points, as John Kasay's 47-yard field goal just cut the 49ers' lead to 7-3 with 5:40 left in the first quarter.
The Panthers had a couple of third-down conversions in a modest 10-play, 36-yard drive which also included Steve Smith's first catch of the day and another drop by Smith on what would have been a 20-yard gain.
The Panthers heard a shower of boos from the home fans, however, when on third-and-8 from the 49ers' 28, they ran DeAngelo Williams to the right and lost one instead of trying to pass.
After that, however, Kasay knocked his field goal through to cut the 49ers' lead to four.
