JOHANNESBURG -- South Africa's track governing body has lost a major sponsor because of its handling of world champion runner Caster Semenya's gender tests.
Nedbank said in a statement Thursday that it feared its reputation could be harmed by "the unfortunate negative situation."
The bank acted a week after Athletics South Africa gave a vote of confidence to its leader, allowing Leonard Chuene to keep his job after he admitted lying about his role in the testing.
Semenya won the 800 meters at the world championships in Berlin in August.
The International Association of Athletics Federations said before the final that it had ordered gender tests. Such matters are usually kept confidential, and the IAAF has been criticized for going public.
