(CNN) -- South Africa's Caster Semenya became the latest high-profile athlete to pull out of the troubled Commonwealth Games, with a back injury cited as she withdrew Tuesday.
Semenya has only just returned to the track after being controversially sidelined for 11 months, having been forced to undergo gender tests after her 800m victory at the world athletics championships in Berlin last year.
The 19-year-old was added to the South Africa squad in August and has scored a series of convincing victories over her specialist distance to serve notice she would be favorite for gold in New Delhi.
But she will not be making the trip after the full extent of her problem became clear.
The statement on the official website of the South Africa Sports Confederation and Olympic Committee confirmed the news.
