Simon withdraws with knee injury

MELBOURNE, Australia -- Gilles Simon of France has withdrawn from the Australian Open because of a right knee injury.

The 15th seed has been off the tour treating a chronic knee injury for almost two months. He last played in November at the Paris Masters.

The 25-year-old Frenchman said he traveled to Melbourne on Saturday against his doctor's advice and realized during pre-tournament practice he wasn't ready to play at his top level.

Simon said he "figured it's more likely this would end bad than good."

Simon's departure leaves No. 10-seeded Jo-Wilfried Tsonga and No. 32-seeded Jeremy Chardy as the only remaining seeded Frenchmen playing in the Australian Open, which starts Monday.
