Amir Khan has officially announced his retirement after a glittering 17-year career in professional boxing. Khan had a 10-year amateur career before turning professional in 2005, going on to become the light welterweight world champion.
His wins included victories over Marcos Maidana, Devon Alexander, Marco Antonio Barrera and Dmitry Salita - before suffering a few devastating losses to Canelo Alvarez and Terence Crawford.
The 35-year-old was stopped in the sixth round of his latest fight with bitter rival Kell Brook at the AO Arena in Manchester in February, and looked like his better days were behind him as he was convincingly defeated.
