They did the same thing when Serra got the belt from GSP, sent him of to to the reality show. I think this is bad business in my opinion. Ufc has to remain a sport, and hence have some kind of standard for their champions to compete ( injuries aside ). If they don't, then it just ends up another popularity contest and we never really know who the best is. These guys, health allowing, need to defend their titles.
Serra never even defended his belt after he got it from GSP, and ultimately lost it do to injury on tuf show. They need to figure something else out.
Serra got hurt coaching at his own gym, not on TUF.
The UFC stopped being sports-based a while ago, Dana is more worried about the entertainment aspect of things.
