VIENNA, Dec 22: Austrian Stefan Koubek, the world number 60, said on Wednesday he had been banned from competition for three months for doping.

Koubek blamed an injection from an Austrian doctor aimed at treating a wrist injury for producing traces of a banned substance, triamcinolon acetonid, found in his urine by a test during this year's French Open.

Koubek said the ban was imposed by the International Tennis Federation (ITF) after a hearing on Tuesday, adding that he would appeal once the written ruling was issued. "I have acted correctly," Koubek said in a statement. -Reuters
