GENEVA (Reuters) -Former Wimbledon and French Open champion Simona Halep had her four-year doping ban cut to nine months by the top court for global sport on Tuesday, making the former world number one eligible to return to competition immediately.

Halep was initially banned for four years for two separate anti-doping rule violations. But the Lausanne-based Court of Arbitration for Sport (CAS) ruled that her suspension should be reduced to nine months, a period she has already served.

"The CAS Panel has unanimously determined that the four-year period of ineligibility... is to be reduced to a period of ineligibility of nine (9) months starting on 7 October 2022, which period expired on 6 July 2023," CAS said.

Now that the 32-year-old Romanian is eligible to compete, she could be granted a wild card to this year's French Open or Wimbledon.

"Throughout this long and difficult process, I have maintained my belief that the truth would eventually come out, and that a just decision would be reached, because I am and always have been a clean athlete," Halep said in a statement.

"I cannot wait to return to the tour."

Halep was suspended in October 2022 after she tested positive for roxadustat - a banned drug that stimulates the production of red blood cells - at the U.S. Open that year.
