For former Wolf Pack quarterback Colin Kaepernick, Sunday's wild card round matchup pitting his San Francisco 49ers against the Green Bay Packers in frigid Green Bay, Wis., wasn't even all that cold.

Kaepernick, after all, had quarterbacked the Wolf Pack on a cold late November night against Boise State in 2010, leading the Pack to a stunning 35-34 victory over the third-ranked Broncos.

Why would Sunday's game, which was five degrees at kickoff, be any different?

It wasn't.

Kaepernick, a 2010 graduate of the University, passed for 227 yards and a touchdown and ran for a game-high 98 yards. His clutch play led the 49ers on a game-winning drive - including a key 11-yard scramble on third down - that culminated with Phil Dawson's 33-yard field goal as time expired, giving San Francisco a 23-20 victory. In all, Kaepernick accounted for 325 of the 49ers' 381 yards in total offense. San Francisco advances to the divisional round of the playoffs against Carolina on Sunday.

It marked the third time in the past year that Kaepernick, a four starter at Nevada from 2007-2010, had led the 49ers to a win over the Packers.

Kaepernick, who was born in Wisconsin and grew up as a Packers fan while going to elementary, middle and high school in northern California, played the game without long sleeves.

"I've played in cold weather games," Kaepernick was quoted as saying afterward on 49ers.com. "It's more mental than anything." He then mentioned his experience at the University as one of the reasons why the cold wasn't a factor. "In Nevada, we didn't have jackets, beanies or heaters," he said with a smile.
