Former world number one Simona Halep has filed an appeal with the Court of Arbitration for Sport against her four-year ban from competition for breaking anti-doping rules.

The 2019 Wimbledon singles champion was suspended by an International Tennis Integrity Agency tribunal in September, having been provisionally suspended in October 2022 after returning a positive test for the banned substance Roxadustat.

The tribunal ruled that the 32-year-old Romanian had committed intentional anti-doping run violations with reference to two charges, but she has now lodged an appeal with CAS for that finding to be overturned.

If the ban is upheld it means she will not be free to compete again until October 2026, by which time she will be 35 years old.

In a statement issued at the time of the ban, Halep said she had “never knowingly or intentionally used any prohibited substance.”

CAS has not given a timeframe for the appeal to be considered, but noted that she would be free to appeal the court’s decision via the Swiss Federal Tribunal if it is unfavourable.
