Mixed martial arts career

Hailing from Memphis, Tennessee, USA, Jackson had his first taste of combat sport as a wrestler for Raleigh-Egypt High School where his successful career was punctuated by All-State honors. Originally, Jackson had intended on pursuing a career in professional wrestling upon finishing high school, but ultimately ended up extending his amateur career in junior college before discovering mixed martial arts. 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 11 wins and 1 loss fighting for a variety of smaller scale American promotions, including King of the Cage, Gladiator Challenge and Dangerzone.

Pride Fighting Championships

For all his early successes it was not on his native soil but rather in Japan's Pride organization that Jackson rose to fame in the world of mixed martial arts. Entering Pride in 2001 as a previously unknown fighter, Jackson was matched at Pride 15 against fellow wrestler and Japanese superstar Kazushi Sakuraba, who was at that time Pride's most prominent domestic fighter. Jackson lost due to a rear naked choke from Sakuraba, but his performance opened the eyes of Pride's fan base and its executive office.

After beating pro-wrestler Alexander Otsuka in a fight for the Battlarts promotion, Jackson was invited back for Pride 17 where he scored a knockout victory over Otsuka’s training partner, Yuki Ishikawa. In his next fight, Jackson was disqualified for an accidental low blow against Daijiro Matsui.

Jackson then went on to defeat Masaaki Satake, Igor Vovchanchyn, Kevin Randleman and Mikhail Illoukhine in successive Pride bouts. He also made forays into kickboxing with a pair of victories over kickboxer Cyril Abidi, under K-1 rules. In 2002, when Pride Fighting Championships and K-1 were exchanging talent, Jackson was sent to fight kickboxer Cyril Abidi under K-1 rules. The first kickboxing bout between Abidi and Jackson was on July 14, 2002. Many expected Jackson's wild style of striking would not translate into the K-1 ring, thinking he would be outclassed by such a schooled and disciplined striker as Abidi. Instead, Jackson overwhelmed Abidi from the opening bell, and knocked him down less than a minute into the bout. Jackson then scored a hard underhand right to the chin of Abidi, knocking him out only 1:55 into the very first round.

Later in the year, Abidi wanted to prove his loss to the undisciplined Jackson was nothing more than a fluke, and faced him on the New Year's Eve Inoki Bom-Ba-Ye card, again in a K-1 rules bout. Jackson laid a lot of criticism to rest by once again defeating Abidi, this time not by early knockout, but via a clear decision. It would be Jackson's last foray with kickboxing, as he returned to full-time MMA competition after his second win over Abidi.

Around this time, Jackson began stating his intentions to capture the Pride middleweight (205 lb) title from Wanderlei Silva. In the opening round of Pride's 2003 Middleweight Grand Prix, Jackson won a split decision over Murilo Bustamante. Three months later, Jackson defeated UFC fighter Chuck Liddell in the tournament's semi-finals at Pride Final Conflict 2003 by corner stoppage, putting him in place to battle Silva in the tournament finals that night. Jackson fought for the championship against Silva in what was called fight of the year by various MMA media.[who?] After taking Wanderlei Silva down and bloodying him, a stand-up was called by the referee and Jackson was stopped with a series of knees to the head.
Jackson famously slamming Ricardo Arona, while in a triangle choke, for the KO in Pride Critical Countdown 2004.

Jackson continued his Pride career with victories over Ikuhisa Minowa and Ricardo Arona, finishing the latter bout with a powerbomb slam by which Jackson rendered Arona unconscious after Arona had locked Jackson in a very tight triangle choke.

Prior to his rematch with Silva, the notoriously brash Jackson made headlines with the public announcement of his conversion to born again Christianity. In the fight itself, Jackson floored Silva in the opening round and later scored a takedown which led to a series of knees and elbows at the end of the round. Jackson scored another takedown in the second round, but Silva escaped to his feet and proceeded to brutally knock out Jackson with knee strikes to the head for the second time.

Jackson's next two bouts were against Silva's Chute Boxe training camp partners. He won a split decision over Murilo "Ninja" Rua, but fell to Rua's younger brother, Shogun Rua, via TKO in the elimination series of Pride's 2005 Middleweight Grand Prix, where Rua broke several of Jackson's ribs early in the fight and proceeded to win by soccer kicks to Jackson's head.

Jackson was berated by his trainers following the loss to "Shogun". Soon after, Jackson was contacted by veteran boxing and MMA trainer Juanito Ibarra, who saw potential in Jackson's natural abilities but viewed his profane reputation as a downfall. After a short conversation, Jackson entrusted Ibarra, a fellow born again Christian, with the managerial and training direction of his career.

Jackson then earned wins over Hirotaka Yokoi and Yoon Dong-Sik before leaving the Pride organization.

After Pride

On May 16, 2006, the World Fighting Alliance announced it had signed Jackson to a multi-fight deal. He defeated Matt Lindland in by split decision at WFA: King of the Streets on July 22, 2006. "He is a good fighter," Jackson said. "I trained hard. He is an Olympic silver medalist. So much respect to him. I knew I had to bring it." The match turned out to be a tough one for the Memphis native who got caught in guillotine choke holds twice. "Rampage" managed to get out both times, and slammed Lindland a few times before cutting the bridge of his nose with ground and pound on his way to the win.

UFC

Jackson lands a right hook that results in the knock-out of Chuck Liddell at "UFC 71" capturing the Light Heavyweight Title.

On December 11, 2006, Zuffa, the parent company of the UFC, announced it had acquired select assets from the World Fighting Alliance, which ceased operations as part of their sales agreement. Jackson's WFA contract was one of the assets acquired.

In an interview on the UFC program Inside the UFC, Jackson said it was finally time for him to enter the organization, and that he had not before because of his friendship with UFC fighter Tito Ortiz. Jackson said that because Ortiz was one of the biggest stars in the UFC, and that both were fighters in the same weight class, he did not want to interfere.

Jackson made his UFC debut at UFC 67, where he knocked out Marvin Eastman, avenging an early career loss.

At UFC 71 on May 26, 2007 Jackson faced UFC Light Heavyweight Champion Chuck Liddell in a title rematch of their 2003 Pride bout. Approximately 90 seconds into the first round, Jackson caught Liddell with a right hook to the jaw that sent him down to the mat, whereupon Jackson pummeled him for a referee stoppage at 1:53 seconds to capture the UFC Light Heavyweight.

Jackson then defeated Pride Middleweight Champion Dan Henderson at UFC 75, on September 8, 2007 in London, England via unanimous decision to unify the two organizations' titles.

The Ultimate Fighter 7

On December 9, 2007 it was announced by Dana White at Spike TV's Video Game Awards show that Jackson will be one of the two coaches of The Ultimate Fighter 7. At the conclusion of the season, Jackson fought the other coach and number one contender Forrest Griffin at UFC 86. During the show Jackson showed his temper after his fighters repeatedly lost to Team Forrest. Going into the semifinals only 2 of Jackson's original fighters made the cut while Forrest had 6 of his fighters advance. In the finale Team Griffin's pick, Amir Sadollah beat Team Rampage's top fighter C.B. Dollaway via armbar in the first round.

On July 5, 2008 he fought Griffin for the light heavyweight championship at UFC 86. In the first round of the fight Rampage wobbled Griffin with two solid power punches, and soon after knocking Griffin down. Rampage's power proved to be problematic for Griffin as Rampage tagged him throughout the fight. In contrast, Griffin pushed the pace of the fight from start to finish and stayed much more aggressive than Jackson for most of the fight with multiple leg kicks and by mounting Quinton and landing elbows and punches to his head. In later rounds Jackson managed to take Griffin down twice and work his own ground game, almost executing his signature power bomb. Many took note as Jackson was showing obvious discomfort from the effects of the leg kicks. The next three rounds were described by Sherdog as "somewhat uneventful" with Rampage searching for the knockout punch while Griffin threw whatever he could with long jabs, leg and body kicks. Griffin was awarded a unanimous decision with the scores 46-48, 46-48 and 46-49 in what many considered an upset. After the fight both Griffin and his coach Randy Couture expressed that they thought the fight was close, and Rampage's coach, Juanito Ibarra, had planned to protest the unanimous decision with the Nevada State Athletic Commission. However, after speaking with the commission about his complaint, he decided not to file because he was informed that even if the judges scores were changed to his satisfaction, the fight would still result in a victory for Griffin by a majority decision. Soon after the fight, Jackson fired his long time trainer/manager Ibarra There were talks of an immediate rematch after the fight.

Following the loss of his belt, Quinton was involved in a hit and run incident and a high speed police pursuit in California, following charges which he would plead guilty to. He is scheduled to be sentenced on January 7, 2010.

Back on track

Jackson's next fight, at UFC 92, would be against Wanderlei Silva, the only man to beat Jackson twice. Jackson avenged his previous defeats by knocking Silva out with a vicious left hook in the first round.

The fight was notable for some controversy surrounding the conclusion of the match, as Jackson followed Silva to the ground with another three punches before referee Yves Lavigne called the fight. Yves was unsuccessful at protecting Silva from the second and third punches. Some have stated that Rampage should be punished for continuing to hit a downed opponent. However, it is common in MMA matches for a few strikes to land while a referee is in the process of stopping a fight. Notably, all of Rampage's punches landed before the official stop time of 3 minutes and 21 seconds into the first round. After a brief celebration, Rampage returned to check on Silva and tapped on Silva's chest in a gesture of sportsmanship.

Jackson's next fight was against Keith Jardine at UFC 96 on March 7, 2009. It was announced before the fight that if Jackson won he would fight Rashad Evans for the Light Heavyweight Championship and if he lost Lyoto Machida would fight for the title instead. Jackson then won the fight by unanimous decision with many believing that his knockdown of Jardine in the final seconds of the third round swayed the outcome of the fight. However, an injury suffered by Frank Mir postponed his scheduled title unification fight with Brock Lesnar from UFC 98, and Evans is expected to defend his belt as the main event then instead; Jackson had stated he would like to fight Rashad, however, he suffered torn ligaments in his jaw that will require surgery and five weeks of no contact. Therefore, Lyoto Machida will replace Jackson, and then Jackson is expected to fight the winner of the Machida vs. Evans.
