UFC on FOX 5 drew 4.4 Million viewers, smashing the last event which did 2.4 Million viewers. I'd say that's a solid rating, and a great increase in viewers. And next they have Mighty Mouse vs. Dodson as a main-event
Rampage vs. Teixeira should bring in viewers though since Rampage is a pretty big draw among casuals.
Also, Mark Hominick announced yesterday that he's retiring from MMA. Dude didn't have the best record, but always came to fight, and you could always count on him having an exciting fight. And he's never been the same ever since his team mates death before the Korean Zombie fight.
