By the time night falls on Sunday and the Buffalo Bills’ home game against the New York Jets goes final, it will mark the end of an era. There will never be a regular-season game played at the old Highmark Stadium again, quite a sobering fact as the mammoth new Highmark Stadium towers across the street.

As we all know, this Sunday marks the last regular-season Buffalo Bills game at the original Highmark Stadium. Unless something magical happens during the playoffs, Sunday will be the last game ever in the stadium before the team moves across the street.

It could be the final farewell to the old Highmark Stadium Sunday when the Buffalo Bills take on the New York Jets. If you want to be part of history, here's what you need to know.

The venue, which opened as Rich Stadium in 1973 before changing its name to Ralph Wilson Stadium from 1998 to 2015, will host its final NFL game Sunday.

The current Highmark Stadium will see its last game for thousands of Bills fans who have come to know it as home.
