given the time-lines,
Jones manager has stated it will be the end of the year or superbowl show (Feb 4, 2012) - sidenote is the superbowl show still a major event if there is no football and just another numbered event?
Aug 6, 2011 Evans vs Davis (Ufc 133)
Aug 27, 2011 Silva vs Okami (Ufc 134)
Sept 24 or Oct 8, 2011 St.Pierre vs Diaz (Ufc 135 or Ufc 136)
If Evans gets passed Davis, he is still promised the title-shot, in that case i can see Rampage (providing he beats Hamil) vs Machida rematch for #1 contenders. If Evans loses, then Rampage sneaks back into #1 contender spot.
The earliest we see either super-fight is Feb 4, 2012 in my mind. More likely is GSP vs Silva catchweight and Evans vs Jones, both on the same card.
