Mosley vs. Forrest I, II.
It was finally announced that Mosley would be defending his WBC and Lineal welterweight titles against Vernon Forrest (33-0, 26 KOs). The fight took place at the Madison Square Garden Theater in New York City on January 26, 2002. The Ring Magazine welterweight title was also at stake. Mosley was knocked down twice in the second round as he went on to lose a unanimous decision, his first loss in his professional career.

Light middleweight.
Mosley's first fight at light middleweight was scheduled to take place on February 8, 2003 against former IBF light-middleweight title holder Raúl Márquez at the Mandalay Bay Events Center in Paradise, Nevada. The fight ended in a no contest when Mosley accidentally head butted Marquez twice in round three, which caused two very bad cuts above the eyes of Marquez. Mosley earned a $2 million purse for the fight.
Mosley vs. De La Hoya II.
Mosley and De La Hoya faced each other for the second time on September 13, this time with De La Hoya's "The Ring", WBC, WBA and lineal light middleweight championships on the line. Mosley defeated De La Hoya by a controversial 12 round unanimous decision and joined the exclusive group of world boxing champions that have reigned in three or more divisions. Many fans had Oscar easily beating Mosley in this rematch but judges scored it differently regardless of De La Hoya landing over 100 more punches. Mosley testified in 2003 that he injected himself with the notorious doping agent EPO as he prepared for his light-middleweight title fight against Oscar De La Hoya, according to grand jury transcripts and doping calendars.
Mosley vs. Wright.
Mosley made the first defense of his unified WBC, WBA Super and The Ring Magazine world light middleweight titles on March 13, 2004, against IBF champion Ronald Wright (46-3, 25 KOs) at the Mandalay Bay Resort & Casino in Las Vegas. Prior to taking this bout, Mosley turned down an offer to fight Félix Trinidad in a bout that would have seen him receive $10 million. Wright, who was a 5-to-2 underdog, won the fight via a unanimous decision. Judges Dave Moretti and Chuck Giampa scored it 117-111, while Paul Smith had it 116-112 all in Wright's favor. In the fast-paced bout, Mosley was unable to get on the inside. Wright's southpaw stance made it difficult for him, as he threw jabs and straight left to both the face and body of Mosley. CompuBox stats shows that Wright out-landed Mosley landing 250 punches to 166 from Mosley. In the post-fight interview, Mosley said about the Trinidad fight being in jeopardy, "It was not a mistake. I have no regrets. I wanted to find out who was the best in our division. I was fighting for history." Mosley earned $2.1 million, while Wright was paid $750,000.
Mosley vs. Wright II.
Instead of the big money fight against Félix Trinidad, Mosley fought Ronald Wright in a rematch on November 20, 2004, at the Mandalay Bay Resort & Casino. The fight was for the WBC, WBA Super and The Ring Magazine world title. Wright was stripped of the IBF title on April 19, 2004, because he agreed to have a rematch with Mosley instead of defending the title against the mandatory challenger Kassim Ouma. The fight aired live on HBO. The fight went the 12 round distance. Both fighters were tired during the last round and clinched for most of it. After the final bell rang, both fighters showed respect to each other and embraced in the ring. One judge had it had it 114-114 even, whilst the other two scored it 115-113 in favor of Wright, meaning he scored back to back victories over Mosley. Wright landed 119 punches more than Mosley.
Mosley vs. Estrada.
Following his consecutive losses to Wright, Mosley was on a comeback trail to rebuild and once again challenge for a world title. His next fight took place at Caesars Palace in Las Vegas on April 23, 2005, against David Estrada (18-1, 9 KOs) in a scheduled 10 round bout. The fight went the distance as Mosley was announced the victor. There were two wide scores of 99-91 and 98-93 and a closer margin score of 97-93. The fight wasn't focused on if Mosley won, but more how dominant he would be in doing so. Mosley received $500,000 for the fight.
Mosley next fought five months later in September against undefeated former Mexico welterweight champion Jose Luis Cruz (33-0-2, 28 KOs) in 10 round bout. Much like the Estrada fight, Mosley won a unanimous decision with scores of 96-94, 97-93, and 98-92.
Mosley vs. Vargas I, II.
In November 2005, negotiations were complete and a fight between Mosley and former light middleweight champion Fernando Vargas (26-2, 22 KOs) was confirmed as a WBA light middleweight title eliminator. The fight was scheduled to take place on February 25, 2006 live on HBO PPV at the Mandalay Bay in Las Vegas. Mosley was guaranteed $3 million from the fight plus percentages of the PPV revenue. Mosley won the bout via 10th-round technical knockout after Vargas' left eye was completely closed. Vargas claimed the cut and closure of his eye was not due to a punch, but because of clash of heads. At the time of stoppage, two judges had Mosley was ahead on two cards at 86-85, 86-85 and the third judge had Vargas ahead 86-85. The fight exceeded financial expectations generating 415,000 buys and $18.6 million in revenue.
A rematch was made to take place on July 15 at the MGM Grand Garden Arena in Las Vegas. Mosley was to earn $4 million plus a percentage and Vargas had a base purse of $3 million plus upside on the pay-per-view. Mosley floored Vargas with a left hook in the sixth and Vargas had a very hard time in getting up. Referee Kenny Bayless stopped the fight moments later. At the time of the stoppage, Mosley had won every round on all three judges' cards. Mosley was quicker than Vargas, easily winning rounds with his speed and combinations. At the time of stoppage, the scorecards were much more close than the first fight with Mosley winning 5 rounds to non on all three scorecards. The attendance for the bout was 9,722. After the fight Mosley said, "When I was in the ring I remembered watching Oscar fight Vargas, and he threw that perfect left hook. I was bouncing around and I saw the opportunity and I threw the perfect left hook." Mosley also talked about moving back down to welterweight. HBO confirmed the bout did 350,000 buys, generating $17.5 million in revenue.
Return to welterweight.
Mosley vs. Collazo.
Despite being in position to challenge for the WBA light middleweight title, Mosley decided to return to the welterweight division. In January 2007, Mosley and former WBA welterweight champion Lus Collazo (27-2, 13 KOs) announced that they would meet on February 10, 2007, at the Mandalay Bay Hotel in Las Vegas, Nevada in a fight billed as "Battle at the Bay". The interim WBC welterweight title was at stake because then full WBC champion Floyd Mayweather Jr. had planned to move up to light middleweight to challenge Oscar De La Hoya. There was no confirmation as to whether Mayweather would stay at 154 or return to 147 after that bout. Mosley knocked Collazo down in round 11 with a right hook and went on to win a fairly one-sided fight with judges scoring the fight 119-108, 118-109 and 118-109. Mosley was guaranteed $1 million for the fight.
Mosley vs. Cotto.
It was announced on August 15, 2007 that Mosley would challenge undefeated Miguel Cotto (30-0, 25 KOs) for his WBA welterweight title. The fight, being billed as "Fast & Furious" was announced to take place at the Madison Square Garden in New York on HBO PPV.
On fight night the attendance was 17,135. Cotto landed the better shots in round one and most of round two, however, Mosley landed some good rights at the end of the second. Both landed big shots in round three with Cotto momentarily rocked by a right hand. The two fighters then had some good exchanges in the fourth. Round five was close, but Cotto appeared to be taking control in the sixth. Mosley adjusted and tried boxing from the outside in the seventh round. The boxing continued in the eighth as Mosley moved and Cotto pursued. Mosley hurt Cotto in the ninth round but Cotto fought back gamely at the end of the round. Mosley dominated the first half of the tenth, but Cotto rallied in the second half. Mosley pressed in the eleventh, but Cotto landed some great counter-punches to win the round. Possibly thinking he had the fight won, Cotto stayed out of range in the final round. Two judges scored the fight 115-113 and the third judge had it 116-113 all in favor of Cotto, who retained his WBA title and gave Mosley his fifth professional loss. Both fighters landed 248 punches with Coto have the better connect rate due to throwing 101 fewer punches. Mosley showed his professionalism, saying "Good luck champ. You're a real warrior" to Cotto, on his way out of the ring. Mosley earned a purse of $2 million and the fight garnered 400,000 PPV buys.
Return to light middleweight.
Mosley vs. Mayorga.
In August 2008, it was announced that Mosley would fight at light middleweight against former world champion Ricardo Mayorga (28-6-1, 22 KO's). The fight was to take place at Home Depot Center in California on September 27, 2008. The first time since 2000 that Mosley would fight in his home state. The fight was for the vacant WBA Inter-Continental light middleweight title. Mosley was guaranteed $1 million. During the first three rounds of the bout, the harder puncher appeared to be Mayorga, who landed right hands from long range. Mayorga's roughhousing mixed with his usual showboating antics seemed to bother Mosley, who appeared more uncomfortable and agitated. In recklessly lunging in with wild power shots of his own Mosley wound up falling into more clinches and getting caught with punches he should have avoided. Mosley settled down and found the distance in the fourth round and took the next three rounds by timing Mayorga with overhand rights that landed and occasionally following up with short hooks and single body shots. Mosley continued with right hands in the seventh and eighth rounds. Mosley was able to land single power shots in the late rounds, but threw very few combinations. At times Mayorga beat Mosley to the punch with lead right hands. Near the end of the eleventh round, Mosley landed a right hand that splattered blood from Mayorga's mouth. With less than a minute left in the bout, put Mayorga down on his hands and knees. Mayorga got up on unsteady legs; Mosley stepped in with a short, lead left hook that put Mayorga flat on his back at the bell, resulting in the referee waving the bout off. At the time of stoppage, two judges had Mosley ahead with scored of 107-102 and 105-104, whilst the third judge had Mayorga ahead 105-104. Had the fight gone to scorecards, Mosley would have won via unanimous decision due to the last round being a 10-7.
Second return at welterweight.
Mosley vs. Margarito.
Prior to one of the biggest fights of his career, Mosley began training with Naazim Richardson. Mosley regained the WBA (Super) welterweight title from Antonio Margarito on January 24, 2009 at the Staples Center in Los Angeles. Mosley, now 37 years old, came into the fight as a 4–1 underdog with the bookies after Margarito had spectacularly stopped Cotto 6 months earlier. Prior to the bout, very few gave Mosley a chance of prevailing, with the prevailing view that Margarito was too strong and young for Mosley. The conventional wisdom was that this was a mismatch, which would end in a brutal retirement-forcing stoppage for "Sugar" Shane. A comparison of their last fights; the aforementioned destruction of Cotto by Margarito and a last-gasp knockout by Mosley in a hard twelve-round struggle against Mayorga did not bode well for Mosley. Some predicted a massacre. And it was – only it was Margarito that was ruthlessly clubbed about the ring, unable to land any meaningful shots.
Mosley eventually TKO'd Margarito in the ninth round, after appearing to win every round up until then, in a massive upset. Sugar Shane utterly dominated Margarito, using his superior hand speed, pinpoint accuracy, consistent body punching, countless huge right hands to the jaw and tying up when Margarito backed him into the ropes, to wear Margarito down and stop him—something that many seasoned boxing observers thought was nigh-on impossible. After knocking him down with a series of heavy overhand rights at the end of the eighth round, Margarito was unable to avoid punches during a heavy barrage from Mosley early on in the ninth, forcing the referee to step in as Margarito slumped to the canvas a second time. Margarito had never previously been stopped. It was a sensational win for Sugar Shane and propelled him back to the upper echelons of the welterweight division and the sport of Boxing, in addition to further cementing his legacy as one of the best fighters in his era.
The fight was marred in a controversy after Mosley's trainer, Naazim Richardson diligently spotted a gauze knuckle pad accessory in Margarito's hand wraps. California State Athletic Commission officials had Margarito re-wrap his hands and took the pad for testing: a state laboratory likened the substance to plaster of Paris. Margarito and trainer Javier Capetillo would be suspended for a year by CSAC: this effectively banned them from boxing across the United States, as suspensions in one state are usually also enforced by other commissions. Later investigations determined that Margarito was likely loading his gloves for several other fights as well, including his title win over Miguel Cotto.
The fight was for Margarito's WBA title and the vacant Lineal welterweight championship of "Cyber Boxing Zone (CBZ)". "The Ring" did not recognize this bout for its vacant welterweight championship despite the fact it pitted "The Ring" #1 ranked welterweight, Antonio Margarito, vs. "The Ring" #3 ranked welterweight, Shane Mosley. Coming in the bout, Margarito had just TKO'd the previous "The Ring" #1 ranked welterweight and current "The Ring" #2 ranked welterweight, Miguel Cotto. After the fight, Mosley was named "The Ring"'s #1 ranked welterweight.
Mosley vs. Mayweather.
It was announced that on May 1, 2010, Mosley would fight undefeated Floyd Mayweather, Jr.. Boxing purists had called for the fight for over ten years. Mosley was scheduled to fight WBC champion Andre Berto in a unification fight, but Berto had to pull out after an Earthquake in Haita killed some of his family members. Mosley's WBA title was not on the line because Mayweather refused to pay WBA sanctioning fees. On the fight night, Mosley stunned Mayweather with two right-hand shots in the second round. Mayweather recovered well and dominated the remainder of the fight with superior reflexes and his effective counter-punching style, eventually beating Mosley in a wide decision 119–109, 119–109, and 118–110 on the scorecards to win Mosley's "lineal" welterweight championship.
On May 22, 2010, Mosley was stripped of his WBA (Super) welterweight title, due to not making a mandatory defense, which in turn made WBA Champion Vyacheslav Senchenko the sole WBA titlist in the welterweight division.
Second return at light middleweight.
Mosley vs Mora.
On June 30, 2010 it was announced Mosley would next fight former WBC light middleweight champion Sergio Mora (22-1-1, 6KOs) at the Staples Center in Los Angeles on September 18. An official press conference took place at the end of August. The bout ended up being a highly disputed split draw, where many people thought that Mosley narrowly won the closely contested bout (boxing analyst website Boxrec had it 114-112 for Mosley). The judges scored the bout: Mora 115–113, Mosley 116–112 and 114–114. Punch stats showed that Mosley landed 161 of 522 punches (31%) compared to 93 of 508 thrown (18%) by Mora. The result was booed by the crowd, who began chanting "Canelo! Canelo!" Mosley felt the decision was fair, "We both fought hard. It was good fight, a good decision."
Third return at welterweight.
Mosley vs. Pacquiao.
On May 7, 2011, Mosley lost the fight to Manny Pacquiao for the WBO welterweight title at the MGM Grand in Las Vegas. Rapper LL Cool J performed as Mosley first entered the arena, while vocalist Jimi Jamison of the rock band Survivor sang "Eye of the Tiger" as Pacquiao approached the ring. Pacquiao knocked Mosley down in the third round using a one-two capped with a left straight. Mosley was left dazed by the knockdown but managed to stand up. Mosley floored Pacquiao in the tenth round with a push, but referee Kenny Bayless inexplicably ruled it a knockdown. None of the judges seemed to have bought it judging from the scores. Replays showed that Pacquiao was throwing a punch off balance, had his right foot stepped on by Mosley's left foot and went down with a little help from Mosley's right hand. Bayless apologized to Pacquiao after the fight for the mistake. Pacquiao gained one-sided verdicts from all three judges (119–108, 120–108, and 120–107). Due to Mosley's defeat, Pacquiao looked at a November 12, 2011 match-up, a third fight with Juan Manuel Márquez.
Third return at light middleweight, and first retirement.
Mosley vs. Álvarez.
In February 2012 it was announced that Mosley would fight 21 year old, highly regarded light middleweight champion Saul "Canelo" Álvarez (39-0-1, 29 KOs) on the Mayweather Jr.–Cotto PPV undercard on May 5 for the WBC light middleweight title at the MGM Grand in Las Vegas. Mosely entered with a record of 2-3-1 in his previous six bouts dating back to November 2007. At 40, Mosley was 19 years older than Álvarez. Álvarez was guaranteed $2 million whilst Mosley took the smaller amount of $650,000. Among those in attendance were Sugar Ray Leonard, Thomas Hearns, Bernard Hopkins, and Oscar De La Hoya.
The fight went to scorecards with Álvarez winning a one-sided decision with scores of 119–109, 119–109 and 118–110. ESPN scored the fight wide 118–110 for Álvarez. Álvarez landed more than half the punches he threw (348 of 673). According to CompuBox, it was the most an opponent had landed on Mosley in the 34 fights that they have tracked from his career. Álvarez paid respect to Mosley in the post-fight interview through a translator, "This was a great experience. I felt really good and I want to thank Shane for giving me this experience. He's a great fighter, a true veteran. I tried to knock him out. He took a lot of punches, but it didn't work." Mosley landed 183 of 745 punches (25%). Mosley spoke about stepping back from boxing, "His defense was really good and he was really fast. He can go a long ways. When the kids start to beat you, you might need to start going to promoting. I didn't expect him to be that fast or that good.
Mosley officially retired after this bout, ending his career with a record of 46-8-1, 39 KO's. He went 0-3-1 in his last 4 fights.
Comeback.
Mosley vs. Cano, Mundine.
On March 19, 2013, Mosley announced he was coming out of retirement to fight 23-year-old Pablo Cesar Cano (26-2-1, 20 KOs) in Cancún, Mexico. The fight was set to take place on May 18, 2013.

Mosley fought Australian former professional rugby league footballer Anthony Mundine (44-5, 26 KOs) on November 27, 2013 at Allphones Arena in Sydney, Australia. The fight was due to take place on October 23, but Mosley dropped out due to contractual demands not being met, according to his promoter Richard Schaeffer. In the contract, it stated that the remaining $700,000 of Mosley's $1 million purse was due to be paid by 5pm. Mosley lost the fight after Mundine scored a technical knockout during round 6.

Second retirement.
Mosley announced his second retirement on December 7, 2013. He stated that he plans to become a trainer, to train his son, Shane Jr., and other young fighters.

Final comeback in 2015.
Mosley vs. Mayorga II.
On July 9, 2015, Mosley made a comeback announcement declaring he would fight former rival Ricardo Mayorga (31-8-1, 25 KOs) at a catchweight of 154 pounds on August 29 at The Forum in Los Angeles. On August 14, Don King filed a lawsuit, which stated that Mayorga still had a promotional contract with him dating back to 2009. Mayorga made a return to boxing in 2014. Legal documents showed that Mayorga, upon his return in 2014, signed a Memorandum of Understanding, confirming that his contract with King still stands. The contracted weight was changed to 158 pounds. At the weigh in, Mayorga came in 7.4 pounds heavier than the limit. Mosley also came in overweight. In the end, Mayorga weighed 165.4 pounds with Mosley much lighter at 159.8 pounds. During the face-off, Mosley's girlfriend, who was also helping promote the fight, soaked Mayorga, emptying a water bottle over his head. Mayorga did not react, although later appeared to slap her backside. Mosley immediately erupted, putting his hands on Mayorga's throat. Many outlets, including the WBC claimed it was all staged, to which Mosley's camp called the WBC appalling. The fight went ahead as planned. Mosley won the fight via 6th-round TKO following a body shot, which dropped Mayorga to his knees. The referee began the count, to which Mayorga did not beat.

Mosley was said to be excited about the potential fight and told World Boxing News, "I might take the fight with Liam Smith, but they say we must have a rematch clause." He went on to say that if Smith wanted a rematch, he would have to take it within eight weeks or after October 2016, due to plans already made for early 2016. By the end of October, Mosley pulled out of the negotiations as he would not accept the rematch clause. In a statement he said, "There's no way I should have taken that fight for less than a million and I took it damn near for free, but they blew it over an immediate [rematch]. It's strange." Mosley believed Smith should have been more grateful in fighting him.
