The Shanghai Masters is heading into quarterfinal action later on today without one of the tournament's top contenders.
Spain's Rafael Nadal was handed a surprise loss yesterday in his opening match of the tournament, falling in straight-sets 6-3, 7-6 to Spanish compatriot Feliciano Lopez.
Nadal came down with acute appendicitis a few days ago, which left him bedridden and uncertain if he'd even be able to compete.
He was asked about when he might have his appendix removed.
"My feeling today and my answer today, honestly, is I am going to do it after the World Tour Final. But you never know, it depends how things improve. I want to do it at the end of the year, not now."
