South African star succumbs to undisclosed back injury.

After a successful return to the track this summer following an 11-month hiatus due to a controversy surround her gender, reigning women’s 800-meter world champion Caster Semenya of South Africa has withdrawn from next week’s Commonwealth Games in Delhi, India due to an undisclosed back problem.

“It would serve no purpose to have an athlete in Delhi who was struggling with any sort of injury that would compromise performance,” explained team doctor Shuaib Manjra.

Semenya, who won the 800 meters in a meet record 1:55.45 at last summer’s IAAF World Championships in Berlin, posted a season’s best of 1:58.16 in Milan earlier this month.
