during day two of the Nitto ATP World Tour Finals at O2 Arena on November 13, 2017 in London, England.

Rafael Nadal has pulled out of the remainder of the ATP Finals following a three-set loss to Belgium's David Goffin.

Nadal entered the season ending tournament under a fitness cloud after missing the Paris Maters with a knee injury.

“No, I am off,” Nadal said after going down 7-6, 6-7, 6-4 on Tuesday morning AEST.

“My season is finished. Yeah, I had the commitment with the event, with the city, with myself. I tried hard. I did the thing that I had to do to try to be ready to play. But I am really not ready to play. Is about the pain.

“I cannot hold with enough power to keep playing. I tried, but seriously it was a miracle to be very close in the score during the match. It really doesn’t make sense.

“I know what I have to do. I know all the things that happened in the past when I had these things, and I know the treatment that I had to do. I know the periods of time that I need to work. Then if the treatment works or not, we will see.”

Earlier in the day, Grigor Dimitrov defeated Dominic Thiem 6-3, 5-7, 7-5.
