Promo video leaks Buffalo's new uniforms

The Buffalo Bills' new uniform design apparently has been revealed.

A "Madden NFL 12" promotional video briefly posted on YouTube showed highlight clips of the game, including shots of Bills receiver Steve Johnson, outside linebacker Chris Kelsay safety Donte Whitner in the new duds.

A league source confirmed the uniforms shown in the clip -- an homage to the ones worn from 1975 through 1983 -- were the real deal.

As of 10:30 p.m. ET, the video still was available on the EA Sports official site. Keep your eyes peeled at about the 14-second mark (thanks to Bleacher Report writer Chris Trapasso for the Twitter tip).

For a mental picture of what the uniforms will look like, think the Joe Ferguson-era Bills but with a contemporary take.

The helmets will be white with the blue charging buffalo and gray facemasks. Jerseys will have broad stripes on the shoulders instead of the sleeve bottom. Pants will be blue or white, the opposite of the jersey. Blue pants will have red-between-white piping. White pants will have red-between-blue piping.

Socks will have blue-and-white striped tops, and players will have the option to wear blue or white shoes as opposed to black. Belts are believed to be gray.

It's difficult to judge when trying to picture the new uniforms in your mind and without a vivid photo.

But it's a clean, classic look I think will go over well with the fans.
