The Green Bay Packers have been wearing throwback jerseys for several years now, dating back to the 2010 season. First, the team sported a 1929-era throwback, notable for its blue numbers inside a yellow circle on the front of the jersey. In 2015, they switched to a design that honored the franchise’s uniforms circa 1937-1948, which remains the current alternate jersey for the 2018 season.
Since instituting the alternates in 2010, however, the Packers have worn these alternate uniforms no more than once each year, even though league rules allowed teams to wear alternates for two games per season.
