Article of www.azcentral.com: One wonders if the UFC titel belts are made out of poisonous lead. Anderson Silva (above), the UFC's middleweight champ, like heavyweight champ Brock Lesnar before him, has bowed out of his next title defense. Silva, according to mmajunkie.com, had bone chips removed from his right elbow in October, and the joint has reportedly proved slow to heal. Silva will not fight Vitor Belfort on Feb. 6 in UFC 109 and reportedly likely won't be ready to fight until April. The two were supposed to fight on Jan. 2 at UFC 108 but that was also pushed because of Silva's injured elbow. What now for the UFC? How is the UFC going to stay relevant in the early part of 2010 with two of its biggest stars out for a while? Sound off below.
