U.S. Open semifinalist Yanina Wickmayer was suspended for one year by a Belgian anti-doping tribunal Thursday, accused of failing to report her whereabouts to drug-testing officials three times.

The Flemish regional tribunal called the punishment "reasonable."

Tribunal spokesman Koen Uman said the suspension takes immediate effect, but Wickmayer can appeal the decision.

The 18th-ranked Belgian has denied any wrongdoing and said on her website she planned to appeal to the Court of Arbitration for Sport.

She's scheduled to play in a tournament in Bali this week.

Another Belgian tennis player, 2002 Wimbledon semifinalist Xavier Malisse, also was suspended by the tribunal for breaking the whereabouts rule.

Wickmayer's suspension came as a surprise because a prosecutor recommended she receive only a warning for missing three tests over 18 months.

The tribunal said Wickmayer's failure to live up to anti-doping rules required a suspension.
