These champions shouldn't be getting injured like this. It's mainly happening during sparring. Just off the top of my head we have RDA, Aldo, and Cain recently. At this point I'd rather see a possible "under prepared" (in the sense that they didn't spar as much as normal) champion show up to the fight, than reoccurring injured champions throwing entire fight cards into disarray. This is a fast moving, constantly evolving sport and guess what folks, staying healthy is the most under appreciated aspect of it, in fact it could be argued that staying healthy is a skill unto itself. A champion that trains smart, rests well and stays healthy is of a higher skill caliber than one who gets injured. It's as simple as that. Time for a new standard here, if you get injured as champ, you can kiss your belt goodbye until you adopt the proper training practices to stay healthy, because obviously that part of your game is still lacking and until it improves you're not champion caliber.
