GREEN BAY, Wis. — The bitterly cold forecast for Sunday's NFC wild-card game at Lambeau Field concerned San Francisco 49ers coach Jim Harbaugh. So twice, on Saturday and again before kickoff, he asked his quarterback, Colin Kaepernick, to reconsider his attempt to play in short sleeves and without gloves.
Both times, the Wisconsin-born Kaepernick declined.
“I'm a little hardheaded at times,” Kaepernick said. “I played in cold-weather games before. I feel it's more mental than anything.”
By nightfall, Kaepernick proved his mastery of the elements in San Francisco's 23-20 victory against Green Bay.
Maneuvering on a brown field with bare dirt between the hash marks, Kaepernick led San Francisco back from a 17-13 deficit to take the lead with a little more than 12 minutes to play. On the final drive, Kaepernick improvised a key 11-yard run after a pump fake, setting up Phil Dawson's 33-yard field goal as time expired.
It may not have been record cold for an NFL game, but the conditions were brutal — 5 degrees at kickoff, with a wind chill of minus 10. And the winning kick sent 49ers players running from the sideline to celebrate, shedding their long scarlet coats.
It was San Francisco's fourth consecutive victory against the Packers in the past two seasons, the second in the playoffs. The 49ers advance to face the host Carolina Panthers in a divisional-round game Sunday.
Kaepernick completed 16 of 30 attempts for 227 yards and a touchdown and ran for another 98 yards.
“We did not get it done as far as keeping the quarterback in the pocket,” Packers coach Mike McCarthy said.
The runs, Harbaugh said, were largely unscripted.
“There wasn't a whole lot called out there today,” Harbaugh said. “Our receivers were getting grabbed. I think Colin saw that and just took matters into his own hands. He gets around the edge so fast. If it was a yard, it was 20. It was unbelievable.
