The Packers are one of the toughest tickets in pro sports. Green Bay's season-ticket waiting list is about 30-years long, and the team reports it has sold out every home game since November 1959.

But incredibly, tickets for the Packers' NFC playoff game Sunday against the Giants, at Lambeau Field, were still available as of late Friday afternoon. Yahoo Sports reports it found tickets on Ticketmaster from the Packers, as well as on the resale market.

How is this possible? You can't really blame the weather. Sure, the game-time forecast is calling for 15-degree temperatures, but Packe

rs fans have braved much more frigid conditions. Recall that infamous 1967 Ice Bowl NFL championship game between the Packers and Cowboys, where the wind chill reached more than 40 below.

It's not like Packers fans aren't excited about the team either. Green Bay has rebounded from mediocrity at midseason to win six games in a row.

At least Packers fans who can't go to the game will still be able to watch at home, thanks to the NFL's decision to drop its blackout rule in 2015. Could that rule change be a factor in the game's slow ticket sales? Expect that to be subject for debate if the game actually does not sell out.
