Amir Khan banned for two years from all sport after testing positive for prohibited substance
Amir Khan has been banned for two years from all sport after being found guilty of having ostarine in his system on the night he lost to Kell Brook last year. Ostarine is a banned performance-enhancing drug and Khan, who retired from boxing in May 2022, received a positive test for the drug following a urine sample. Ad After the positive result, Khan's case was referred to an independent tribunal, which ruled out “deliberate or reckless conduct”.
