Sometimes taking time off from the Octagon can benefit you, while other times it can send a fighter into a downward spiral.
Whether it went good or bad for the fighter, a UFC return is always memorable for the fans.
At UFC 43, Kimo Leopoldo returned to the Octagon after a seven-year absence from the UFC and having not fought for more than a year. Kimo made short work of Abbott by taking him to the ground and choking him out in the first round. It was a successful return for Kimo, but he was unable to put together a winning streak.
In his next fight at UFC 48, Kimo was finished via TKO in the first round by
The late Evan Tanner was a former UFC middleweight champion and a much-respected fighter.
At UFC 59, he defeated
And at UFC 82, he was ready. He fought top middleweight Yushin Okami, but things didn't bode well for Tanner, who had little to offer against the power and size of Okami, and ended up getting knocked out in the second round.
Even as a former champion, Tanner was unable to do enough to pull off the comeback. Tanner went on to lose a tough-fought split decision in his next bout, against
At UFC 103, Vitor "The Phenom" Belfort will return after a four-year hiatus from the Octagon, where he will face former UFC middleweight champion
Despite the decision loss, Belfort would bounce back by demolishing
"The Phenom" was back this time, and in his next fight he captured the UFC light-heavyweight belt by defeating
A follow-up loss to Tito Ortiz at UFC 51 forced him to pack his bags and head for Japan, where he fought in the PRIDE organization.
After his UFC 74 win over
Meanwhile, Lesnar was making an impact in MMA. When Couture finally resolved things with the UFC, he was scheduled to return to defend his heavyweight title against Lesnar at UFC 91.
Although Couture did well throughout the fight, he got caught with a right punch that crumpled him to the canvas, where Lesnar was able to finish off the hall of famer with a barrage of hammer fists.
Couture has always been known for overcoming the odds, but the odds were literally too big that night, as a new champion was crowned.
Most of the current fighters got hooked on MMA because of one man, Royce Gracie. Gracie had the ability to make anyone tap out in a fight, no matter how big or how strong his opponent was.
He was the winner of UFC 1, UFC 2 and UFC 4. Eleven years after leaving the Octagon, he returned to face the most dominant welterweight fighter at the time and then-champion Hughes at UFC 60.
Hughes proved that this time size and strength mattered and that MMA had evolved greatly since the days of a prime Royce Gracie. Hughes TKO'd Gracie in the first round, which was enough for the legend to call it quits in the Octagon once and for all.
The rivalry between Ken Shamrock and Tito Ortiz boiled over after Ortiz defeated and flipped off Shamrock's friend and training partner,
Shamrock had not fought in the UFC since 1996. Unfortunately for Ken, his return against Ortiz in UFC 40 was disastrous, as he was dominated by the champion for three rounds before his corner stopped the fight.
This lost seemed to be the first of many as Ken Shamrock went on a downfall from there, winning only two of his next seven MMA fights, including two more losses at the hands of Tito Ortiz.
Former UFC heavyweight champion Frank Mir was mowing down the competition in the UFC heavyweight division before suffering a severe motorcycle accident in 2004.
Unable to defend his newly acquired belt, Mir was stripped of the title and had to undergo surgery and rehab before getting back into the octagon. Mir finally returned in 2006, at UFC 57, against Marcio Cruz.
Although physically able to return, Mir wasn't 100 percent mentally ready for a comeback, and it showed. Cruz dominated Frank and TKO'd him in the first round. It seemed as if Mir had nothing to offer in the fight.
Mir was able to miraculously get his career back on track and go on to beat
At UFC 46, B.J. Penn became UFC welterweight champion when he choked out Matt Hughes. Afterwards, he signed a contract with a rival promotion and was stripped of his belt.
He eventually returned at UFC 58, against top welterweight contender Georges St. Pierre. The fight was a dream match for most UFC fans and the winner would also get a shot at the champion Hughes.
Penn came off strong in the first round, using his superior boxing skills to bloody St. Pierre. Unfortunately for Penn, he gassed out in the second round and slowly got picked apart by St. Pierre, who did enough to win a split decision.
The return fight was not one Penn likes to remember -- the loss haunts him to this day. He went on to rebound and eventually capture the lightweight title against
Jens "Little Evil" Pulver was the first UFC lightweight champion, having dominated the division with his superior stand-up skills and knocking out the competition.
He left the UFC after his title defense against B.J. Penn in 2002, only to return in 2006 at UFC 63. There was a lot of hype surrounding the return of Pulver, but the hype wasn't enough as UFC newcomer Joe Lauzon crashed Pulver's comeback party with a shocking 48-second knockout win.
Lauzon later proved he was a good fighter and one of the top prospects in the lightweight division. In his next fight, Pulver lost a grudge rematch to Penn and decided to cut weight and fight in the WEC.
A disappointing loss to Chuck Liddell at UFC 57 sent Randy Couture into retirement. One of the greatest fighters had finally had enough and left. But he returned to author one of the greatest comeback stories in UFC history.
At UFC 68, Randy returned to fight the considerably bigger UFC heavyweight champion, Tim Sylvia.
Couture stunned the 6-foot-7 giant eight seconds into the fight with a punch that sent the champion to the canvas. He went on to dominate Sylvia to win a decision and the title, doing so at the age of 44.
