The Northern Kentucky River Monsters are a professional indoor football team based in Highland Heights, Kentucky. The River Monsters began play as a charter member of the Ultimate Indoor Football League for its inaugural 2011 season spending one season in the UIFL before reaching an agreement with league management to leave. After a two-year hiatus, they River Monsters returned in 2014 as a member of the Continental Indoor Football League. The River Monsters play their home games played at The Bank of Kentucky Center. On June 6, 2011, it was announced that the UIFL and the River Monsters mutually agreed to part ways, leaving the team free to join another league. However, the UIFL had a lease agreement with the arena, which hampered the likelihood the River Monsters would play in Highland Heights in 2012. The team had been mentioned as a charter member Stadius Football Association, but that league never got off the ground.
