Minnesota Vikings v Green Bay Packers

Minnesota and Seattle players will be getting some high-tech help while playing in what's expected to be one of the coldest NFL games ever.  Players on both teams will be wearing specially-designed underwear meant for cold-weather football. 

The undergarments are designed by a Minnesota company.  The Sunday wild-card playoff game in Minneapolis is expected to be one of the coldest in NFL history, with a wind chill minus-10.
