South Africa sprinter Carina Horn has been provisionally suspended after violating anti-doping rules.
Horn tested positive for Ibutamoren and the anabolic agent LGD-4033, according to the International Athletics Federation’s Athletics Integrity Unit.
The 30-year-old is the first female South African to run sub-11 seconds in the 100m, clocking 10.98 seconds.
She was expected to be part of the national team at the World Championships in Doha later this month. (Courtesy BBC Sports)
