Casper had been listed as a possible expansion location for the Central Hockey League but the league ceasing operations in 2014. The ECHL could be a possibility as there are four teams located in neighboring states (Boise, Idaho; Rapid City, South Dakota; West Valley City, Utah; and Loveland, Colorado), three of which were already in the ECHL.
- Casper Bobcats (Western States Hockey League, 2018-2019) ceased operations
- Casper Coyotes (Western States Hockey League, 2014-2018) renamed Casper Bobcats when sold
- Casper Wranglers (American Frontier Hockey League, 1993-1995) become Central Wyoming Outlaws
- Central Wyoming Outlaws (American Frontier Hockey League, 1995-1998) fold
