In a recent interview with Ariel Helwani, Dana make it very clear Anderson will not be on the 1st Fox show, but he is waiting on something this weekend to decide what the Fox show main event will be. Looking at the rest of the card, I think it must be the Forest vs Shogun fight he is waiting on. Okami isn't exactly a guaranteed exciting fighter. Neither Big Nog or Schaub are first show on Fox main event exciting. So it must be Forrest or Shogun right?
So assuming Forrest or Shogun, both are certainly great fighters worthy of a main event on Fox. On one hand having Forrest provides a lot of symmetry. Forrest was one of the combatants in the fight which saved the UFC and sent them on the upward trajectory they are on now. So having him on the first network show seems a nice idea. However, who would he fight to promise an exciting fight and a compelling story? I've had a few drinks, but I just cannot think of anyone near as compelling as the combination of Shogun vs Machida.
Shogun vs Machida part III is almost guaranteed to be an exciting fight. Both are are stand-up specialists that new viewers could presumably enjoy. The story of a tie breaker for the next title shot is a gimme. So all told I think that is what Dana is waiting on. I want to say Forrest for the symmetry of it all, but I just cannot think of promised match up that has the kind of story the 1st fight on Fox needs. So end of day, I think he is waiting on Shogun. If Shogun wins, I think we'll see Shogun vs Machida in a number 1 contender bout as the main event on Fox.
