The "Ice Bowl" between the Packers and Cowboys in 1967 stands as the coldest game in NFL history, with the temperature at kickoff recorded at -13 degrees.
Sunday's wild card game might out-freeze that record and the weather might be as big of a concern as the 49ers.
The Packers practiced just twice this week before Sunday's playoff contest with San Francisco. But Mike McCarthy said the players are actually ahead of schedule.
"We were able to get done what we needed to get done Thursday and Friday," McCarthy said. "I feel very good about our week of preparation."
Part of this week's practice was held outdoors, as the Green and Gold anticipates sub-zero temperatures during the game.
"It was windy, which I thought was great. Any time you get a chance to handle the football in the wind, it's an opportunity to take advantage of it," McCarthy said.
"We actually spent more time out there than we normally do, just doing extra ball drills and things like that."
As kickoff approaches, Sunday's forecast seems to be getting worse. And while the team is taking advantage of practicing outdoors this week, the players have their own take on preparing for these frigid temperatures."
"Once it gets below zero, cold is just cold. I don't think you can rank it any different," Packers guard T.J. Lang said.
Wide receiver James Jones expects Aaron Rodgers to throw the ball just as hard in the cold as he would in 80-degree weather.
"Make sure you got some real soft gloves on, hooking the ball in. Catching is more important than yards after the catch once it starts getting this cold," Jones said.
A year ago, Eddie Lacy was playing in the BCS national championship game in Miami. The rookie plans to go sleeveless in his first NFL playoff game at Lambeau.
"If I have sleeves, I feel like I'm gonna fumble or something. I don't know," Lacy said. "Just stay with no sleeves. I'm comfortable that way."
A brave decision as Lambeau Field prepares to live up to its nickname as the "Frozen Tundra" on Sunday.
