A week after stating his fight at UFC 144 would not be his last career fight, Quinton “Rampage” Jackson is now stating his next fight will actually be his last – for the UFC.

Jackson went to Twitter to declare that he will fight once more in the UFC, but will then leave the organization.

“I will fight whoever they put in front of me,” said Jackson. “I always have, but it will be my last fight in the UFC. I have other things on my mind.”

Following the announcement, fans began to respond with questions, including if Jackson is retiring, or just leaving the UFC. He responded, stating “I didn’t say I would be done fighting, I just said I’m not fighting for the UFC. I said I have other things on my mind.”

“Why should I stay? I don’t need them or anybody else negative dealing with my carrie [sic] (career).”

Jackson has a 7-4 record in the UFC, dating back to his organizational debut at UFC 67 against Marvin Eastman in February 2007. He defeated Chuck Liddell via knockout to earn the UFC light heavyweight title three months later. He would go on to lose the belt to Forrest Griffin via decision at UFC 86 in May 2008.

After fighting twice more over the next year, Jackson took over a year off from the UFC to begin his acting career. He starred in 20th Century Fox’s The A-Team, which was released in June 2010. Since that time off, Jackson is just 2-3, with losses to Rashad Evans, Jon Jones, and Ryan Bader. The loss to Jones, which took place at UFC 135 in September 2011, was for the UFC light heavyweight title. He lost via 4th round submission, his first submission loss since he lost to Kazushi Sakuraba in his first career Pride fight in July 2001.

After his loss to Bader at UFC 144 last month, Jackson spoke openly about his pre-fight training with Fighters Only magazine. In the interview, Jackson admitted to using testosterone replacement therapy after being prescribed it by a doctor due to a knee injury.

“I almost pulled out but then I went to see the doctor and he told me to talk to an age-management doctor,” explained Jackson. “So I went and talked to them and they tested me and said my testosterone was low; they prescribed me testosterone, to bring my testosterone levels back up to levels where I can be like… so that I am the same as young people, like when I was 25, and it would help build my knee up. I hurt my knee like a month ago and I only did three shots of testosterone but it put a lot of weight on me, a lot of muscle on me but it healed me knee up good enough to where I could fight.”

Jackson mentions the weight he put on caused him to weigh 211 pounds at the pre-fight weigh-ins, 5 pounds over the light heavyweight limit. He was fined 20% of his purse, and went on to lose to Bader via unanimous decision.

Regarding his future, Jackson did not mention an opponent he had in mind. However, after UFC 135, Jackson openly campaigned for a rematch with Mauricio “Shogun” Rua, who he fought in Pride. Another name that has been mentioned is a rematch with Dan Henderson, whom he defeated in September 2007 at UFC 75.

Regardless of who he fights, Jackson seems set on making this his last trip into the Octagon.
