The AFC East division championship banner for the Buffalo Bills is now officially hanging at City Hall.

Buffalo officials formally unveiled the banner Monday night in Niagara Square.

The Bills clinched the division with a win over the San Francisco 49ers a few weeks ago and are now fighting for the 1 seed in the AFC.

"I want to invite Bills fans from across our region and beyond to visit the City Hall," Buffalo Acting Mayor Chris Scanlon said. "Make sure you come by, take a selfie with our banners and celebrate with our team as they enjoy their fifth consecutive AFC East championship."

The Bills will be back in action on Sunday against the New England Patriots.

The game has been flexed from 1 p.m. and will now kick off at 4:25 p.m.
