The Bills–Titans rivalry is a National Football League rivalry between the Buffalo Bills and the Tennessee Titans. The series originated during the American Football League's inaugural season in 1960, as both the Titans, then known as the Houston Oilers, and Bills were charter teams in the league, playing as divisional opponents in the AFL's East division. Despite being moved to different divisions following the AFL–NFL merger, the Bills and Oilers/Titans have had several heated competitions since, including two of the most memorable moments in NFL playoff history, namely The Comeback and the Music City Miracle. Since 1999, several games have been decided by less than a touchdown.
