The chances are very doubtful, he is a smaller guy for 145er's and he would be overpowered in the UFC's LW division. I heard recently he walks around at something like 153lbs and he would be fighting guys that are cutting down from upwards of 170. He has become the face of the WEC over the past year and he will continue to be their poster boy if he gets the title back. Look for him to stay with the WEC for a long long time until he clears out every possible contender then maybe he would move up. But its highly unlikely
i'd love to see him move up and out to dream. faber vs aoki/hansen/JZ would be awsome fights. aoki and faber is my lightweight dream match all the way.
