Highly doubt it, he trains at X-Gym which is Anderson's gym in Brazil, Feijao's down there too and everyone would probably lean towards Anderson, but I doubt Jacare would even do it to begin with.
Weidman's supposed to be back early summer, I guess they could fight but it wouldn't be ideal in terms or promoting, Rockhold or Bisping has to be his next fight unless he fights at 205 again but I think he said he was done fighting at 205 after Bonnar. Maybe the UFC believes in Bisping more than we do, who knows but I don't see anyway Bisping can win this, his cardio is much better but his chin gets touched in just about every fight it seems.
If Bisping loses, It'll probably be Silva/Rockhold, UFC vs. SF/Title unification and all that good stuff but Rockhold's no different than Bisping or Belcher, he's a striker and thus Anderson will probably eat him alive. I know I'm the number one Weidman guy on this board and keep hugging his nuts but that fight is so much more better than Rockhold or Bisping vs. Silva.
