Interviewer: One thing we've noticed recently is the Facebook fights. Is that going to continue with the ongoing Fox deal, or is that going to go away with the prelims and all that stuff?

Dana: Yeah it will go away when the Fox deal starts, which is in January. Because all that programming now, I mean the reason we did the Facebook fights was because nobody could see those fights. So we put them up on Facebook as an option for fans, because we always love to give more fights. But with the fact that Fox wants to pick up all these fights, they'll be on television now.
