Are these the new Green Bay Packers alternate uniforms?

These potential leaked uniforms are pretty slick.

Back in March, Packersnews.com noted per the NFL's five-year rule, the Green Bay Packers would be moving on from the blue uniforms with small yellow circle and numbers inside.

While it wasn't unveiled what the uniforms would be, Twitter user @PrimeTimePhil found the uniform above floating on the Nike website with a "Coming Soon" notion, and that is what's rumored to replace the other old-school unis.

Paired with bigger numbers, these uniforms stem from the 1937-49 era, per the team's website. They were also worn in 1994.
