England’s Football Association banned a second-division player for two years on Wednesday in a doping case.
Barnsley defender Bambo Diaby cannot play until January 2022 after testing positive for the banned substance higenamine.
The U.K. Anti-Doping agency said the substance is thought to help burn fat and act as a stimulant. It is found in supplements to facilitate weight loss.
"While Bambo Diaby admitted the charge, he did not establish how the higenamine entered his system,” the soccer body said, explaining why a two-year ban was mandatory.
Diaby tested positive after a league game against Blackburn last November. The 22-year-old player started his career in Spain and was previously signed by Sampdoria.
