The ITF have suspended French tennis player Richard Gasquet following his positive test for cocaine, pending a hearing.
The International Tennis Federation says an anti-doping tribunal should be assembled within 60 days to hear the case.
Gasquet says he is gathering evidence to prove his innocence, despite both his "A" and "B" samples coming back positive for cocaine.
Traces of the drug were found in the 22-year-old Gasquet's urine sample at the Sony Ericsson Open, in Key Biscayne, Florida, in March.
"He's suspended until the end of the hearing," ITF spokesman Neil Robinson said. "We're now assembling an anti-doping tribunal. The ideal timeframe is within 60 days, but people have to fly in from all over the world for it."
