MMA Mania reports that in addition to Leben/Bisping, the card may be on Spike TV a la UFC 75:
In addition, and this is the shakiest bit of information we are passing along, the show will possibly air on SpikeTV for FREE similar to UFC 75: “Champion vs. Champion.”
Well, here’s the thing. They are much, much more worried about alienating the thousands of fans who have bought tickets than alienating some fans with a letdown of a show here (see UFC 78). With all the money they have pumped into the expansion, they don’t want to ruin the good will they have built up by providing a middling card to people who paid good money to see Chuck Liddell.
Throughout the day I’ve heard they are making efforts on a variety of fronts to add names that matter to this card. However in multiple cases the guys they have approached have been unable to fight. They are still trying though, and I wouldn’t be surprised if they add another.
