NFL Game Summary - Green Bay at San Francisco

San Francisco, CA (Sports Network) - Colin Kaepernick kicked off his first full season as San Francisco's starting signal-caller with a resounding win over the same team he torched in last year's NFC Divisional Playoffs.

Kaepernick threw for 412 yards and three scores, while Frank Gore's go-ahead 1-yard touchdown late in the fourth helped the reigning NFC champion 49ers claim a 34-28 victory over the Green Bay Packers on Sunday in the season- opener for both teams at Candlestick Park.

Kaepernick completed 27-of-39 passes and became the first San Francisco quarterback to throw for 400-plus yards since Tim Rattay accomplished the feat on Nov. 10, 2004.

Anquan Boldin, acquired from Baltimore for a sixth-round pick in the offseason, quickly asserted himself as Kaepernick's favorite target, hauling in 13 passes for 208 yards and a score.

Vernon Davis added six catches for 98 yards and two touchdowns for the 49ers (1-0), who dropped a heartbreaking 34-31 decision to the Ravens in Super Bowl XLVII back in February.

Aaron Rodgers finished 21-of-37 passing for 333 yards, three touchdowns and one interception, while Jordy Nelson and Randall Cobb each caught seven passes for 100-plus yards and a score.

Rookie running back Eddie Lacy rushed 14 times for 41 yards and a touchdown for the Packers (0-1), who won the NFC North for a second straight season last year before being bounced in the playoffs by Kaepernick and the 49ers.
