Amir Khan is one of the only boxers who has been able to make a name in his native England and transition that popularity to the United States. 

Khan (33-4, 20 KOs) makes his return to the States for the first time in nearly three years when he challenges Terence Crawford for the WBO welterweight championship on Saturday, April 20 from Madison Square Garden in New York City.

Khan won the 140-pound WBA title from Andreas Kotelnik in July 2009. The 32-year-old made four straight defenses of the belt before adding the IBF strap when he scored a fifth-round knockout of Zab Judah in July 2011. In his next time out in December 2011, the 32-year-old lost the IBF belt by split decision to Lamont Peterson and subsequently lost the WBA strap by fourth-round TKO to Danny Garcia.

“King” Khan bounced back to win five consecutive fights to set himself to make the trek up to middleweight and challenge Saul “Canelo” Alvarez for the WBC belt at a catchweight of 155 pounds. For the first half of the bout, Khan looked pretty good until Alvarez viciously knocked him out in the sixth round.

Following the fight, Khan took nearly a two-year hiatus and has beaten Phil LoGreco and Samuel Vargas in his native England. 

Now, Khan gets the mega fight he’s always been looking for at his natural weight of 147 pounds. Sporting News takes a look at the last five matches of Amir Khan before the biggest fight of his career.

Amir Khan vs. Samuel Vargas

Fight date: Sept. 8, 2018

Result: Khan wins by unanimous decision.

Summary: Khan was expected to run through Vargas to set himself for a big fight his next time out. Things were looking great when Khan dropped Vargas with a vicious right hand. He appeared to be on his way to finishing Vargas off. At the end of the round, Vargas surprisingly sent Khan to the canvas. Khan scored another knockdown in the fifth round. 

Vargas got up and proved to be a game opponent. But Khan’s speed and technical prowess were too much, and the judges scored it 119-108, 119-109 and 118-110 in favor of Khan.

Amir Khan vs. Phil LoGreco

Fight date: April 21, 2018

Result: Khan wins via first-round TKO.

Summary: Khan hadn’t fought in 23-months since the crushing KO defeat to Alvarez. He came out as a man on a mission from the outset. After landing a couple of combinations, he connected with a devastating left hook followed by a blistering right hand to drop Lo Greco. The Canadian got up, but Khan sensed blood. He landed a series of combinations with a hard left hand sending Lo Greco to the mat. The referee had seen enough and the fight was waved off in just 39 seconds to cap off a triumphant return. 

Amir Khan vs. Saul “Canelo” Alvarez

Fight date: May 7, 2016

Result: Alvarez won by sixth-round knockout.

Summary: Khan kept looking for significant bouts with either Floyd Mayweather Jr. or Manny Pacquiao. Failing to secure a fight with either opponent, Khan shifted focus and moved up two weight classes to face the next biggest star in Alvarez. The fight took place at a catchweight of 155 pounds. 

Khan started out using his speed and frustrated Canelo to win the early rounds. Canelo started to figure Khan out, gauged his speed and used what got him to the dance — his power. As the fight wore on, the hard body shots wore Khan down.

In the sixth round, Canelo threw a perfect overhand right hand that slowly sent Khan crumbling to the canvas. Khan’s head smacked the mat, and referee Kenny Bayless stopped the fight.

Amir Khan vs. Chris Algieri

Fight date: May 29, 2015

Result: Khan wins by unanimous decision.

Summary: Khan looked like he could in trouble as Algieri almost knocked him down with a right hand in the opening round. Throughout the early rounds, Algieri was stalking Khan and being the aggressor. In the second half of the fight, Khan figured Algieri out by standing in the pocket and landed numerous combinations to the head and body of Algieri to secure the victory by scores of 115–113, 117–111 and 117–111 to run his winning streak to five.

Amir Khan vs. Devon Alexander

Fight date: December 13, 2014

Result: Khan wins via unanimous decision.

Summary: The fight was set to happen one year earlier, but Khan pulled himself from the contest because it appeared he would be squaring off with Mayweather. Once again, the carrot got taken away from him, so he went back to his original opponent in Alexander. Khan showed the world he was ready to battle the biggest name in the sport by overwhelming Alexander and making it look rather easy using his strength and patented speed in winning a lopsided decision (119-109, 118-110, 120-108).
