World number two Rafael Nadal showed no signs of suffering from appendicitis as he was dumped out of the Shanghai Masters in his opening match Wednesday, days after being diagnosed with the condition.
The Spanish second seed in Shanghai lost 6-3, 7-6 (8/6) to compatriot Feliciano Lopez, after he revealed he was diagnosed with appendicitis on Sunday.
Nadal insisted he was still fit to play the tournament after he was put on a course of antibiotics which relieved stomach pains and helped avoid immediate surgery.
The 14-times Grand Slam winner is competing in his second event since returning from his latest injury layoff, which stretches back to the end of July.
He crashed out of last week's China Open at the quarter-final stage, and admitted he is still far from his best form.
