Amir Khan has been given a two-year ban from all sports after he tested positive for a banned substance following his fight with Kell Brook last year.
UK Anti-Doping said Khan, 36, returned a positive result for the anabolic agent ostarine after losing to Brook in Manchester on February 19 2022.
Khan, who announced his retirement in May last year, accepted a violation of anti-doping rules but said he had not intentionally ingested the substance, an argument accepted by an independent panel following a hearing in January.
A UKAD statement said: “Mr Khan’s two-year ban is deemed to have commenced on April 6 2022 (the date his provisional suspension was imposed) and will expire on April 5 2024.”
Khan was stopped in the sixth round of his grudge fight with bitter rival Brook 14 months ago in what proved to be his final professional bout.
He unified world titles at super-lightweight and faced pound-for-pound stars Saul ‘Canelo’ Alvarez and Terence Crawford during a 40-fight career, featuring 34 wins and six defeats.
The Bolton fighter had launched his pro career in 2005 after winning an Olympic silver medal at the 2004 Athens Games.
Khan became a world champion in July 2009, defeating Andriy Kotelnik on points to secure the WBA super-lightweight title, and he then stopped Zab Judah to add the IBF belt two years later.
A hotly-disputed points loss to Lamont Peterson ended Khan’s world title reign, and he was halted by Danny Garcia while attempting to win the WBC and WBA belts in his next fight.
Khan made an audacious move up to middleweight to challenge Canelo for the WBC belt, suffering a sixth-round knockout loss in May 2016 and was stopped by Crawford in the sixth round of their WBO title fight in April 2019.
He eventually shared the ring with Brook in February 2022, embracing his rival in the ring after their feud was finally ended. (SkySports)
