Over 2 million viewers tuned in during the prime time showing of UFC's first-ever free, live basic cable telecast. "Ultimate Fight Night" knocked out the competition, taking the number-one slot for all cable programming on Saturday night, outdrawing both an NFL pre-season game between the Indianapolis Colts and Atlanta Falcons and ESPN's X-Games.
