Former stock and commodities trader and boxing manager C.J. Comu, and World Arena Rugby founder Buckeye Epstein, have booked a Friday night fight at the American Airlines Center with two former Ultimate Fighting contenders. They've also landed fighting announcer Bruce Buffer, who's known as the official voice of the UFC's octagon-shaped ring. They've even got Mark Cuban's interest in televising the fights on a pay-per-view basis.
