2012 Buffalo Bills season

The 2012 season was the Buffalo Bills' 43rd in the National Football League (NFL), their 53rd overall, and their third and final season under head coach Chan Gailey. The team had hoped to make the playoffs for the first time since 1999, but instead extended the NFL's longest playoff drought.

2012 was the final year on the Bills' current lease at Ralph Wilson Stadium, as well as the final year on the Bills Toronto Series agreement. The league had approved an additional five-year extension of the Toronto series, extending through 2017 on the condition that the Bills and Rogers Communications came to an agreement to do so, a condition that both sides indicated willingness to do. The Bills and the league demanded significant and expensive renovations to Ralph Wilson Stadium as a condition of renewing the stadium lease. The Buffalo News reported renovations could top $200 million. The Bills and Erie County (the owners of Ralph Wilson Stadium) missed the deadline for a long-term agreement in September 2012; however, on December 21, the Bills agreed with Erie County to a 10-year lease on Ralph Wilson Stadium, extending it for at least another seven years.
