Just jacked this from cagepotato:

MMAmania.com can confirm that a main event title fight between newly crowned UFC Light Heavyweight Champion Rashad Evans (13-0-1) and former 205-pound kingpin Quinton Jackson (29-7) could be added to the UFC 96 card at the Nationwide Arena...
  Perhaps the only thing currently standing in the way is time — both fighters face relatively tight turnarounds since their most recent winning performances at UFC 92: “The Ultimate 2008″ on Dec. 27.
Hope that's true and I hope I posted this right. First time FanPost.
