The Green Bay Packers' offensive line is waiting on an all-important game-time decision prior to Sunday's home game against the San Francisco 49ers:

To wear or not to wear sleeves.
"The weather forecast is pretty damned cold," right guard T.J. Lang said, per ESPN Milwaukee. "Probably a game-time decision. I've never worn them in my life, but I don't want to get frostbite. We'll see what happens."
Forecasts in Green Bay currently call for balmy 1 degree weather with wind chills around -18 degrees at kickoff. Those temperatures are expected to sink to -5 degrees with a -28 degree wind chill by game's end.
"I said (to rookie David Bakhtiari), if I'm wearing sleeves, then you're wearing sleeves," left guard Josh Sitton said. "I don't want to be the only one with sleeves on. We'll see. I mean if it's so cold that I need sleeves, I'm putting sleeves on. I don't really care what anybody thinks of me toughness-wise."
Offensive linemen are generally known as the toughest players on a football field and usually shunn the long sleeves regardless of the weather conditions.
With frostbite a real possibility given the bone-chilling temps, these men aren't messing around. Hopefully Packers fans follow their lead and wear as many layers as possible, including the underrated long johns.
