) today confirmed the numbers with an industry source.
Replays of the pre-event preview show are slated for Thursday at 3:05 p.m. ET/PT and Saturday 6 p.m. ET/PT.
The in-depth "Countdown" show focuses primarily on the night's headliner, which came about after UFC light heavyweight champion Mauricio "Shogun" Rua's initial opponent, Rashad Evans, was forced off the card with a knee injury and Jon Jones filled the gap.
A co-headliner between former WEC champs and current UFC bantamweights Urijah Faber and Eddie Wineland, which is expected to earn the winner a title shot, is also examined. Main-card fighters Brendan Schaub and opponent Mirko "Cro Cop" Filipovic also get some attention.
UFC 128 takes place March 19 at the Prudential Center in Newark, N.J.
Thursday's "Countdown" show isn't the only pre-event programming planned for the network. As MMAjunkie.com previously reported, the UFC's longtime cable partner airs "UFC Presents Jon Jones: In the Moment" tonight at 11 p.m. ET/PT.
The channel also airs a pair of UFC 128 preliminary card bouts on Saturday night.
