Montsho has now been officially disqualified from the Glasgow 2014 Commonwealth Games and could face up to a two-year international ban after both her A and B samples tested positive for the stimulant methylhexaneamine.

The 31-year-old was tested on July 29 following her fourth place finish in the women's 400 metres at Hampden Park and after returning a positive result, she requested a B-sample be tested.

That also returned positive and Montsho had until today to request a hearing with the CGF.

However, the CGF has confirmed in a statement today that the athlete informed them in a letter on Wednesday (August 20) that she is waiving her right to a hearing and accepts the results.

The CGF has said its decision, along with all relevant documentation, will be forwarded to the International Association of Athletics Federations for further action in accordance with the World Anti-Doping Agency's (WADA) World Anti-Doping Code.

Following the disclosure of the initial failed drugs test, sources in Botswana claimed Montsho unknowingly consumed an energy drink containing methylhexaneamine, while it was also being claimed she took it inadvertently as part of a flu medication.

Methylhexaneamine is a Class S6 stimulant and is on the WADA Prohibited List.

Montsho won the 400m title at the 2011 World Championships in Daegu before finishing runner-up two years later in Moscow.

She also won the 2010 Commonwealth Games gold medal, becoming Botswana's first-ever gold medallist in any sport.

Before this, at Athens 2004 she became the first Botswanan woman to compete in an Olympic Games in any sport, and eight years later in London, she carried the flag of the southern African nation in the Opening Ceremony, before finishing in fourth place in the final.
