CWG: Athlete Amantle Montsho fails doping test, faces provisional suspension

Former world and Commonwealth champion Amantle Montsho has failed a doping test after the women's 400m final at Glassgow, resulting in a provisional suspension.

Montsho, 31, won Commonwealth gold at Delhi 2010 and the world title in 2011. Her gold medals at Delhi and Daegu were her country's first at a Commonwealth Games and World Championships respectively, and she also won silver at the 2013 World Championships in Moscow, losing out to Great Britain's Christine Ohuruogu in a dramatic photo-finish, the BBC reported.

However, she missed out on a medal at Glasgow as she tied up badly in the final 100m and finished behind the Jamaican trio of Stephanie McPherson, Novlene Williams-Mills and Christine Day.

Montsho also revealed earlier that she would quit athletics after the Rio 2016 Olympics and was aiming to become a basketball player.

A statement from the Commonwealth Games Federation read: The athlete's A sample was found to contain methylhexaneamine, prohibited as a stimulant under class s6 of Wada's Prohibited List.

Upon receipt of the analysis of the athlete's B sample, the court will reconvene to consider the matter further.
