Richard Gasquet will find out on Thursday whether he must serve an extended doping suspension.

The Court of Arbitration for Sport are set to reveal their decision later on Thursday.

The 23-year-old Frenchman failed a test for cocaine in March and served a two-and-a-half-month ban.

He was then cleared in July after the International Tennis Federation's disciplinary panel accepted his explanation that the drug got into his system after he kissed a woman at a nightclub.

However, the ITF, along with the World Anti-Doping Agency, appealed against the decision of their own panel and are seeking a ban of up to two years.

Gasquet attended a CAS hearing in Switzerland last month and a verdict has now been reached.

CAS said in a statement today: "The Court of Arbitration for Sport will issue its decision in the arbitration procedure between the International Tennis Federation, the World Anti-Doping Agency and the French tennis player Richard Gasquet on Thursday, 17 December 2009 at 5.30pm (4.30pm GMT)."

Gasquet, who is known for his elegant game, achieved a career-high ranking of number seven in 2007 after reaching the Wimbledon semi-finals but is now outside the top 50.
