Amir Khan has been banned from boxing for two years after failing a drug test in the aftermath of his defeat by Kell Brook last year.
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. Khan, 36, later announced his retirement but it has now been revealed he failed a drug test shortly after the final bell.
The former world champion tested positive for the banned substance ostarine which can be found in supplements and which can aid muscle growth. Khan was made aware of the failed test last April before being charged two months later.
