MMARated.com has the scoop:

MMARated.com has learned that a light heavyweight bout between Wanderlei Silva and Quinton "Rampage" Jackson has been offered to both fighters for UFC 91 on November 15th and is very close to being finalized.

The addition of Silva vs. Jackson to a UFC 91 card that is already headlined by Randy Couture vs. Brock Lesnar for the UFC heavyweight title would put this pay-per-view in position to be the highest-grossing PPV in UFC history. Currently, UFC 66 holds that distinction since that event - headlined by a rematch between Chuck Liddell and Tito Ortiz - grossed $5,397,300 in live gate revenue and just over a million in pay-per-view buys.

If this goes down it would be the third match up between these elite light weights. Silva took the previous two by brutal KO's and both men are looking for a shot at the title. Expect fireworks if this one goes down.
