There's not many fighters who've provided more entertainment throughout their careers than Amir Khan. After turning pro in 2005, Khan has enjoyed a stellar career.
Here, DAZN looks back at the key highlights from Khan's memorable run in the ring.
2004 - Khan captures silver medal at Athens Olympics. His final loss to Mario Kindelan would be later avenged, but his second-place finish, at 17 years of age, made Khan an instant star.
2005 – Makes professional debut and wastes no time getting his paid career off to the perfect start when stopping David Bailey in the opening round.
2005 – Goes the distance for the first time when he’s unable to stop Baz Carey and has to settle for a deserved points win.
2007 – Incredible fight with Willie Limond sees Khan nearly suffer his maiden career defeat. Khan is heavily dropped in round six but recovers well to win two rounds later.
2008 – Suffers the first loss of his career when he’s blown away in one round by Breidis Prescott. The Columbian was something of an unknown fighter beforehand, but he arrived in style when dropping Khan twice and ending his unbeaten run.
2009 – Fight with Mexican great, Marco Antonio Barrera, is an ideal confidence builder for Khan as he defeats Barrera via technical decision after the legendary boxer suffers a cut.
2009 – Rolls the dice in first world title shot but is handsomely rewarded when schooling Andreas Kotelnik to become WBA champion at 140lbs.
2010 – Unbelievable encounter with Marcos Maidana sees Khan retain his title by the skin of his teeth. After a great start, Khan is rocked late in the fight and spends the championship rounds in survival mode before winning by narrow margins on the cards.
2011 – Unifies the light-welterweight division with dominant victory over Zab Judah to add the IBF strap to his growing list of honours.
2011 – Tough battle with Lamont Peterson sees Khan make a good start before Peterson takes over later in the fight. Two point deductions are costly for Khan as he loses his titles on points.
2012 – Reinstated as WBA world champion following a failed drugs test from Peterson, Khan loses his crown immediately as he’s emphatically blown away in four rounds by Danny Garcia.
2014 – Move to welterweight sees Khan enjoy excellent wins over Luis Collazo and Devon Alexander. His pursuit of a fight with Floyd Mayweather or Manny Pacquiao is unsuccessful though.
2016 – After failing to secure a dream fight at 147lbs, Khan moves to middleweight to face Canelo Alvarez. The gamble doesn’t pay off as Khan suffers horrible knockout to the heavy-handed Mexican.
2018 – Ends two years of inactivity by returning to Britain to defeat Phil Lo Greco and Samuel Vargas.
2019 – Returns to the highest level to take on Terence Crawford in New York City. Khan is second best throughout but after suffering a low blow in round six, Khan can’t continue. Crawford is handed the victory via TKO.
2022 – Long-time rivalry between Khan and Kell Brook is finally settled, and it’s the man from Sheffield who emerges victorious with a stoppage in round six.
2022 – Khan announces his retirement from boxing following a superb 17-year career.
