At the January 27th, 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. This is due to the Thomas and Mack Center is undergoing renovations during the 2015 season. They had planned to return for 2016 season, however their operations were suspended indefinitely due to an inability to find a suitable host venue.
