The potential passing combination of quarterback Colin Kaepernick to wide receiver Anquan Boldin led the San Francisco 49ers to a 34-28 victory Sunday over the Green Bay Packers.

Boldin caught 13 passes for 208 yards and one touchdown, his first game with the 49ers since being traded from the Baltimore Ravens for a sixth-round draft pick.

And Kaepernick passed for a career-high 412 yards and three touchdowns.

He also responded to a late hit from Packers linebacker Clay Matthews, saying afterward: "If intimidation is your game plan, I hope you have a better one."

Besides Boldin, tight end Vernon Davis caught a pair of touchdown passes.

After beating the Packers in the playoffs, the 49ers did it again.

"We knew they were going to come in ready to play after what happened in the playoffs," Boldin said. "We had to come out and match their intensity."
