Former 400m world champion Amantle Montsho has been handed a two-year suspension from competition after failing a drugs test last year.
After finishing in fourth place in the Commonwealth Games final in Glasgow, Montsho tested positive for the stimulant methylhexaneamine.
Both her 'A' and 'B' samples provided positive results, leaving a disciplinary committee to rule that the Botswana athlete will serve a two-year ban.
The 31-year-old has already indicated that she will appeal the ruling before the deadline of March 25.
