Could it happen? http://www.mmaweekly.com/absolutenm/templates/dailynews.asp?articleid=6981&zoneid=13 until Filho fights in the UFC and gets a few wins under his belt, I don't see the average fan making big noise for such a fight. And if it's not going to be a big draw, I don't see the UFC rushing such a fight.
They are extremely close friends, though. Paulo told an interviewer he would never fight him because he is his brother.
Anderson has told Brazillian newsmag Tatame that he would never fight Paulo, so I have no idea where Ed Soares gets the idea it could happen.
