US Open semi-finalist Yanina Wickmayer must wait to see whether she can return to action even though a Belgian court has suspended a one-year ban imposed on her for violating anti-doping regulations.
The International Tennis Federation (ITF) said on Tuesday that they were still considering the judgment by the Court of First Instance in Brussels which suspended the ban, citing administrative errors with the way it was imposed.
"The ITF has now heard from the National Anti-Doping Organisation Flanders and we are seeking counsel from our legal advisors and World Anti-Doping Agency (WADA)," an ITF spokesman said.
Wickmayer, 20, was banned in November after failing to notify her country's anti-doping agency where she could be reached. Fellow-Belgian Xavier Malisse, a former Wimbledon semi-finalist, was also suspended for a year for missing a doping test and twice failing to say where he could be reached.
Malisse also had his ban suspended on Monday.
Both Wickmayer and Malisse announced last month that they were appealing to the Court of Arbitration for Sport.
The ITF has had overall responsible for enforcing WADA doping-controls in tennis since 2007.
