US sprinter Michelle Collins has been reinstated by the IAAF after serving over three years of a BALCO-related suspension.

Her ban for using performance-enhancing drugs was to expire in July, but it was reduced because Collins cooperated with the US Anti-Doping Agency and federal investigators.

The 37-year-old Collins is eligible to try to qualify for the US Olympic trials, which start next month.

"All I want to do now is return to the sport I love," Collins said in a statement released by the Valparaiso Sports Law Clinic, which represented her. "I look forward to competing again."

Collins lost her 2003 world indoor title at 200 metres because it was found she had used banned substances from the controversial Bay Area Laboratory Co-Operative, although she has never tested positive. She later admitted to using banned substances.
