The International Tennis Federation has confirmed a one-year suspension for Belgian tennis players Yanina Wickmayer and Xavier Malisse.
The duo was suspended by a Belgian tribunal this week for failing to report their whereabouts to anti-doping officials three times during 2009.
The ITF said in a statement that it agreed that the players had violated anti-doping rules.
The governing body said it “recognises and respects” the tribunal’s decision, and will “take all steps necessary to enforce” the ban.
Wickmayer, who reached this year’s U.S. Open semifinals, has said she will appeal the ban. She pulled out of this week’s WTA Tour tournament in Bali after the tribunal’s decision was announced.
