Rafael Nadal had successful surgery to remove his appendix on Monday and will remain in the hospital for up to two days to recover. Nadal is now hoping of a comeback in January. He will not play in 2014 again.
"If I play the last two tournaments, I would not be competitive and would have no chance to win. It is better for me to recover. I hope to be back at the start of 2015 ready for anything," Nadal said.
A statement from Nadal's spokesman said the appendectomy was performed at the TEKNON Medical Center in Barcelona by Dr Segura Movellan and his team.
"Everything has gone very well. Thank you for your support," Nadal tweeted in Spanish after the operation.
Nadal first experienced symptoms related to his appendix four weeks ago during a tournament in Shanghai.
Because of the surgery, Nadal will miss next week's ATP finals in London.
