Quinton Ramone Jackson (born June 20, 1978) Japanese: [Kuinton Rampag jakuson];, also known as Rampage Jackson, is an American mixed martial artist and actor. He is a former UFC Light-Heavyweight champion of the world. Jackson rose to prominence in Japan's Pride Fighting Championships where he was noted[citation needed] for his powerful body slams including a knockout victory over Ricardo Arona. In the United States, he is known for his tenure in the Ultimate Fighting Championship (UFC). Jackson is the first person to unify any of the UFC and Pride FC championship belts, defeating Pride Fighting Championships Middleweight title holder Dan Henderson in 2007. Jackson is currently ranked as the #4 Light Heavyweight fighter in the world by Sherdog, MMAWeekly and Yahoo! Sports.[Impressed by the success of other wrestlers in MMA, Jackson decided to try his own hand at the sport. Jackson built up an impressive record of 10 wins and 1 loss fighting for a variety of smaller scale American promotions, including King of the Cage, Gladiator Challenge and Dangerzone.On March 24, 2010, Dana White announced that Jackson signed a new six fight contract with the UFC. Jackson's next fight was against former UFC light heavyweight champion Lyoto Machida at UFC 123 on November 20, 2010. At UFC 123, Jackson met Machida in the main event. Jackson went on to win by a controversial split decision. UFC president Dana White put all doubts to rest and supported the judges decision, he said that Jackson won the first two rounds, no rematch would be needed.
Jackson was expected to face Thiago Silva but Silva had problems in his UFC 125 drug test and was replaced by Matt Hamill on May 28, 2011, at UFC 130. Jackson put on a dominant display, easily defending the decorated wrestlers take downs and winning the striking exchanges. He won the fight via unanimous decision.UFC president Dana White stated that Jackson will face Jon Jones for the UFC Light Heavyweight title. The fight took place on September 24, 2011 at UFC 135.Jackson lost by submission in the fourth round. This is Rampage's first time being finished in the UFC, and his first submission loss since fighting Kazushi Sakuraba.Jackson's style is heavily centered around powerful striking, particularly his boxing. In his Pride FC days, he would often use his wrestling background and tremendous strength to execute slams on his opponent; today he often uses his wrestling skills to defend takedowns. Being very adept at triangulation, he uses his forearms to 'slip' punches past his head and counter. Some analysts have criticized him for his lack of checking kicks; he prefers to take the kicks to his thighs in order to be able to counter with powerful punches. He is also very talented at cover-rolling, a technique that he used to beat former UFC light-heavyweight champion Chuck Liddell. He is well known for possessing tremendous knockout power (in both hands), brutal ground-and-pound, great physical strength and an iron chin.
