The Tropicana, Casino Aztar and Horizon casino in Vicksburg, Miss., have been put up for sale by Fort Mitchell, Ky., parent Columbia Sussex to avoid having to seek bankruptcy protection.
The Tropicana was placed under a trustee after the New Jersey Casino Control Commission denied an application by Columbia Sussex to renew its gambling license.
Evansville Mayor Jonathan Weinzapfel has told the newspaper that two companies have discussed with him the possibility of owning the Aztar.
As part of an agreement reached after the Tropicana license was yanked, Columbia Sussex must sell the Tropicana, Aztar and Mississippi property by June.
The Aztar is threatened by competition from French Lick Casino and by the possibility of Kentucky lawmakers approving gambling.
