BASEL, Switzerland (AP) -Tennis player Richard Gasquet will go before the highest court in sports Tuesday for what he says was a cocaine-tainted kiss in a nightclub.

The World Anti-Doping Agency and International Tennis Federation have asked the Court of Arbitration for Sport in Switzerland to ban him for one to two years.

Gasquet failed a drug test after pulling out injured from a tournament in Florida in March and was suspended. The Frenchman says his positive test resulted from a kiss he gave a woman.

An independent tribunal called by the ITF ruled he was not to blame. He was cleared to play again after serving just 2 1/2 months. A verdict by the top sports court is expected before the end of the year.
