Wickmayer, ranked 16th, was banned for one year in November, along with compatriot Xavier Malisse, for failing on three occasions to report her whereabouts to drug testers under World Anti-Doping Agency regulations.
A Belgian civil court lifted the bans on Wickmayer and Malisse on Dec. 16 pending appeals against their suspensions.

Wickmayer broke Goerges in the fifth and seventh games to take the first set in 38 minutes, but gave up an early break in a second set which lasted almost an hour.
She broke in the fifth game to lead 3-2 but Goerges broke back in the 10th to level the second set at 5-5. Wickmayer immediately regained the break at 6-5 and trailed 15-30 and 30-40 in the 11th game before winning on her second match point.
"It was a tough first match," Wickmayer said. "I've worked a bit on everything (since her last match) and I was glad with the way I played.
"I knew I had to put pressure on her because she's a very good player and the person who applied the most pressure would win. I tried to play aggressive and play into the court and it worked."
Wickmayer last week blamed a breakdown in communication with Belgian doping officials for her ban. Her rise during 2009 into the world's top 50 brought her under WADA's regulations which require athletes to report their whereabouts to drug testers 365 days a year.
Wickmayer, who has never failed or missed a drug test, said Belgian officials sent papers indicating she was in breach of the whereabouts rule to her home in Belgium while she was in Australia.
