The Court of Arbitration for Sport (CAS) will deliver its verdict on Richard Gasquet's positive test on Thursday.
Gasquet, who tested positive for cocaine in Miami this March, received a reduced two and a half month suspension from an independent anti-doping tribunal after he identified a nightclub kiss the night before as the likely source of the positive test. The ITF appealed the reduced length of the ban to CAS.
A positive test for cocaine can carry a suspension of up to two years.
