In late April 2006, Mike Shannahan Jr. Decided to fold the team due to lack of attendance, Issues with the lease at the Family Arena and a steep workmans comp bill. The staff was then let go as the announcement was made that the team would not play in the up coming 2006-07 United Hockey League season. While leaving open the possibility of a sale, owner Mike Shanahan Jr. said that the competition for the sports dollar in the greater St. Louis area meant that the team would likely fold instead of being sold.
