Rafael Nadal is a serious doubt for the season-ending ATP World Tour Finals following his latest injury.
The 17-time Grand Slam winner pulled out of the Paris Masters on Wednesday after picking up an abdominal injury.
His withdrawal means Novak Djokovic will overtake him as world No 1 when the new rankings are released on Monday.
The Spaniard will have next week to recover, but the ATP Finals starts at the O2 Arena in London on November 11 and he admits it’s a case of wait and see.
Asked about his chances of playing at the finals he replied: “I am very sorry but I cannot answer you. I just go day by day, as I did all my tennis career.
“In terms of this kind of a stuff, I have to be checking daily about things how it improves. I would love to be in London of course. But the most important thing for me is to be healthy and have the chance to compete weeks in a row. It’s something that I was not able to do this year, playing only nine events and retiring in two. So that’s the real point.
“I can talk about a pain that bothers me every time that I serve. It would not be fair to say it’s a real injury today but what is sure, if I continue it will be a real injury.
“As you know, when you come back after injuries, and you push a little bit the body at the beginning, some issues can happen.”
