After two weeks of talking trash about the UFC, former light heavyweight champion Quinton Jackson seemingly got his wish in the promise of a contractual release after his next fight with the added bonus of a chance to avenge his past loss to Mauricio Rua. However, two things “Rampage” failed to mention on Twitter during his online assault pertained to his problematic knees and the possibility of going under the knife to fix them.

Jackson saved that nugget of information until Thursday where he again took to the social networking site, this time writing his bout with the Brazilian would have to wait while he got surgery on both of his knees. No specifics beyond that were offered in terms of the procedure or required period of recovery though “Rampage” did state one had been hurt against Jon Jones and the other in training.

“I heal fast (so) don’t trip,” said Jackson, assuring fans he planned to make his way back to the Octagon sooner than later. The circumstances certainly didn’t appear to bring the popular pugilist’s spirits down, as later in the evening he mentioned being “buzzed” and heading to a club in Los Angeles.

With no date set for Jackson-Rua II, nor knowledge of the 33-year old’s actual prognosis, it’s impossible to know exactly how the planned rematch will be affected. The two 205ers first fought in PRIDE with “Shogun” picking up a TKO win in the first five minutes of action.
