The Sin was originally announced one of four teams that were to be introduced to the league in 2008. The other teams were to be Atlanta Steam, Miami Caliente and San Francisco Seduction. When the league took the field in 2009, the Sin were not included in the league's ten inaugural franchises.
At the January 27, 2015, State of the League address, it was stated that the Sin would be playing at Citizens Business Bank Arena in Ontario, California, for the 2015 season due to the Thomas and Mack Center undergoing renovations during the season. They had planned to return for 2016 season, but their operations were suspended indefinitely due to an inability to find a suitable host venue.
